President before election Donald Trump Republican Elected President Joe Biden Democratic

The 2020 United States presidential election in Arizona was held on Tuesday, November 3, 2020, as part of the 2020 United States presidential election, in which all 50 states and the District of Columbia participated. Arizona voters chose 11 electors to represent them in the Electoral College via a popular vote pitting incumbent Republican President Donald Trump of Florida and his running mate, incumbent Vice President Mike Pence of Indiana, against Democratic challenger and former Vice President Joe Biden of Delaware and his running mate, United States Senator Kamala Harris of California. The Libertarian nominees were also on the ballot. This is the closest presidential election in Arizona history, surpassing the previous closest of 1964, in which Barry Goldwater won the state by just under a single percentage point.

Trump carried Arizona in 2016 by 3.5%, and it was considered a vital battleground in this election. The state's bitterly competitive nature was attributed to diversification of Maricopa County, a traditionally Republican stronghold that holds 61.6% of the state's population. Biden became the first Democrat to win Arizona since Bill Clinton in 1996, and only the second since Harry S. Truman in 1948. He is also the first Democrat to win Maricopa County since Truman, with a margin of 2.2%, or 45,109 votes. High turnout among Hispanic/Latino and Native American voters was also seen as vital. Polls of the state throughout the campaign generally showed a Biden lead, albeit by a slender margin. Prior to election day, 11 of the 16 news organizations considered that Arizona was leaning towards Biden; the other five considered it a toss-up. Arizona was the second-closest state in 2020, the only closer state being Georgia, marking the first time since 1948 that the Democratic nominee won both Sun Belt states in the same presidential election (Clinton won each state in separate elections). This was also the first time since 1932 that a non-incumbent Democrat carried Arizona in a presidential election, or that an incumbent Republican lost the state. Arizona weighed in as 4.15 percentage points more Republican than the nation in 2020.

After the election, the Republican-majority Arizona Senate launched a Maricopa County-based publicly-funded investigation into the election fraud alleged by Trump and his supporters. The controversial audit, completed in September 2021, found no evidence to support claims of significant election irregularities. Additionally, the count taken in audit gave Biden a greater lead of 360 votes over Trump than what the earlier, certified results had given.

On April 24, 2024, Arizona Attorney General Kris Mayes announced that a grand jury has indicted eleven fake electors and seven Trump allies, including Rudy Giuliani and Mark Meadows, for their roles in attempting to overturn the results for Trump.

Primary elections

Canceled Republican primary

See also: 2020 Republican Party presidential primaries § Cancellation of state caucuses or primaries

On September 9, 2019, the Arizona Republican Party became one of several state Republican parties to officially cancel their respective primaries and caucuses. Donald Trump's re-election campaign and GOP officials have cited the fact that Republicans canceled several state primaries when George H. W. Bush and George W. Bush sought a second term in 1992 and 2004, respectively; and Democrats scrapped some of their primaries when Bill Clinton and Barack Obama were seeking reelection in 1996 and 2012, respectively.

Of the 57 total delegates, 3 were allocated to each of the state's 9 congressional districts, 10 to at-large delegates, and another 3 to pledged party leaders and elected officials (PLEO delegates). 17 bonus delegates were also allocated.

The state party still formally conducted the higher meetings in their walking subcaucus-type delegate selection system. The legislative district and county conventions were held from February 8 to April 11 to select delegates to the Arizona State Republican Convention. At the Arizona State Republican Convention, which took place on May 9, the state party formally bound all 57 of its national pledged delegates to Trump. A May 15 email from the Arizona GOP stated that "every one of our ... delegates ... elected pledged to support Donald Trump and Mike Pence as the Republican Party's 2020 nominees for President and Vice President!"

The 54 pledged delegates Arizona sent to the national convention were joined by 3 pledged PLEO delegates, consisting of the National Committeeman, National Committeewoman, and chairman of the Arizona Republican Party.

Democratic primary

Main article: 2020 Arizona Democratic presidential primary

The Arizona Democratic primary took place on March 17, 2020, on the same date as the Democratic primaries in Florida and Illinois. Former Vice President Joe Biden won the primary with 43.7% of the vote and 38 delegates, running ahead of Senator Bernie Sanders from Vermont, who received 32.7% of the vote and 29 delegates. No other candidates received any delegates and the only other candidates to receive more than 1% of the vote were Senator Elizabeth Warren from Massachusetts, with 5.8%, and former South Bend, Indiana Mayor Pete Buttigieg, with 4.1%. Both Warren and Buttigieg withdrew prior to the contest. The other candidates on the ballot comprised a collective 1.2% of the vote.

Biden won 13 of 15 counties in the state of Arizona, with Sanders winning Coconino (home to Flagstaff) and Yuma (home to its eponymous city) counties.

The official vote totals reported by the Arizona Secretary of State added up to 86.7%, as the remaining 13.3% of the vote was composed of candidates whose individual vote totals were not reported.

Campaign

Arizona was a heavily contested state throughout the election. Once a reliably Republican state, it has trended more Democratic in recent years, with Trump winning it by just 3.5% in 2016. Compared to past Republicans, Trump's performance was historically weak: Mitt Romney won it with a 9.0% margin in 2012 over Barack Obama, John McCain by 8.5% in 2008 also against Obama, and George W. Bush by 10.5% in 2004 against John Kerry. Arizona was one of just ten states to swing more Democratic in 2016, and its 5.5 percentage point swing was the fourth largest in the country. The swing mirrored a nationwide pattern where suburban voters, formerly the principal Republican voting base, swung deep into the Democratic column. Arizona's leftward swing was also credited to a rapidly growing Hispanic population.

Both candidates spent massive amounts of money on advertising, though Biden outspent Trump 2–1.

October 25, 2020: Campaign rally for Joe Biden at Corona Ranch and Rodeo Grounds in Phoenix, featuring Cher.

Trump visited Arizona significantly more than his opponent, holding 4 rallies in just one week, compared to Biden, who only visited the state once. Trump favored large rallies with thousands of people in attendance, oftentimes without masks and contrary to the advice of health officials.

At his rallies, Trump campaigned with the Republican Governor of Arizona, Doug Ducey, as well as Republican Senator Martha McSally, in a bid to help her win against Democrat Mark Kelly in the 2020 United States Senate special election.

Fundraising

According to the Federal Election Commission, in 2019 and 2020, Joe Biden and his interest groups raised $9,284,978.20, Donald Trump and his interest groups raised $15,506,263.10, and Jo Jorgensen raised $29,078.65 from Arizona-based contributors.

Candidate ballot access

• Joe Biden / Kamala Harris, Democratic
• Donald Trump / Mike Pence, Republican
• Jo Jorgensen / Jeremy "Spike" Cohen, Libertarian

Independent candidates who wished to run were required to submit a nomination petition and financial disclosure form between 120 and 90 days before the primary election. A valid nomination petition required signatures from 3% of unaffiliated registered voters in Arizona as of March 1, 2020. However, the signatories may be of any political party or unaffiliated as long as they have not already signed a petition for a candidate registered in a political party who intends to run in the same election. Petitions may be physical or electronic; in 2012, Arizona introduced E-Qual, an online nominating petition platform.

In-addition, write-in candidates were required to file a nomination paper (including the candidate's name and signature; residence and post office address; age and date of birth; and the length of time the candidate has lived in Arizona) and financial disclosure form by 5:00 p.m. on the 40th day before the election in which the candidate is running – in this case, September 24 – for their votes to be counted. Sore-loser laws prevent candidates who lost a primary election from running in the general election as a write-in candidate. Write-in candidates also may not run if they didn't receive enough signatures to attain ballot access while filing for the primary election or if the candidate did not receive enough signatures to gain ballot access in the general election. The following candidates were given write-in access:

• Howie Hawkins / Angela Nicole Walker, Green
• Jade Simmons / Claudeliah Roze, Independent
• Gloria La Riva / Sunil Freeman, Socialism and Liberation
• Daniel Clyde Cummings / Ryan Huber, Constitution
• President R. Boddie / Eric Stoneham, Independent

Electoral slates

Technically the voters of Arizona cast their ballots for electors, or representatives to the Electoral College, rather than directly for president and vice president. Arizona is allocated 11 electors because it has 9 congressional districts and 2 senators. All candidates who appear on the ballot or qualify to receive write-in votes must submit a list of 11 electors who pledge to vote for their candidate and their running mate. Whoever wins the most votes in the state is awarded all 11 electoral votes. Their chosen electors then vote for president and vice president. Although electors are pledged to their candidate and running mate, they are not obligated to vote for them. An elector who votes for someone other than their candidate is known as a faithless elector. In the state of Arizona, a faithless elector's vote is voided and replaced, but the faithless elector is not penalized.

The electors of each state and the District of Columbia met on December 15, 2020, to cast their votes for president and vice president. All 11 pledged electors cast their votes for President-elect former Vice President Joe Biden and Senator Kamala Harris from California. The Electoral College itself never meets as one body. Instead, the electors from each state and the District of Columbia met in their respective capitols. The electoral vote was tabulated and certified by Congress in a joint session on January 6, 2021 per the Electoral Count Act.

These individuals were nominated by each party to serve as the state's members of the 2020 Electoral College should their party's ticket win the state:

Analysis

In winning Arizona, Biden won Maricopa County, by far the most populous county in Arizona, making it the first time a Democrat had done so since 1948. Biden also became one of only two Democrats to break even 45% of the vote statewide since Lyndon B. Johnson did so in 1964. Biden's statewide winning margin of 0.3% remained out of range for a recount, since Arizona Revised Statutes does not have provisions for candidate- or voter-requested recounts. Furthermore, an automatic recount will only be performed if the margin is lower than 0.1%. This was the first time since 2000 that any county in the state flipped parties.

Arizona was seen as a potential Democratic flip throughout the year, as the state's increasing Hispanic population as well as an influx of retirees and younger college-educated voters were becoming increasingly friendly to the Democratic Party.

Analysts attributed Biden's win in Arizona to several factors, including shifts towards Democrats in the suburbs of Phoenix and an increase in Native American turnout. Trump's attacks on moderate Republicans, including the late Arizona senator John McCain, were also cited as factors that helped Biden, along with Biden's endorsement from Cindy McCain, the widow of John McCain, and former Arizona Senator Jeff Flake. The Biden campaign had released an ad featuring Cindy McCain discussing Biden's relationship with John McCain. Analysts also cited Latino organizing after Arizona Republicans passed controversial immigration laws such as SB 1070.

Hispanic and Latino voters

Biden carried the Hispanic/Latino vote by a 59–40 margin, which was eleven points weaker than Hillary Clinton's 61–31 win in 2016 among Latinos, in spite of her loss statewide. Santa Cruz County, where 83.5% of the population is Hispanic or Latino, swung 12 points more Republican than in 2016, while Yuma County (63.8% Hispanic or Latino) swung 5.1 points more Republican.

Native American voters

Biden easily won Apache County, dominated by the Navajo and Fort Apache reservations; and Coconino County, encompassing the Havasupai Nation and parts of the Navajo, Hopi, and Hualapai nations. Anywhere from 60 to 90% of the Navajo Nation's 67,000 registered voters voted for Biden. In Pima County, Biden won the precincts encompassing the Tohono O'odham, San Xavier, and Pascua Yaqui reservations, often with over 90% of the vote.

Concurrent elections

The presidential election was held concurrently with elections to the House of Representatives and Senate. In the 2020 United States Senate special election, incumbent Republican Martha McSally, who lost the 2018 Senate election but was appointed to the Senate to replace Jon Kyl (who in turn replaced the late John McCain), ran for re-election, but was defeated by Democrat and former astronaut Mark Kelly. Kelly was widely expected in polling and forecasts to outperform Biden due to McSally's unpopularity, and ended up doing so by 2.05 percentage points. It also corresponded with 2020 Arizona Proposition 207, a referendum to approve the legalization and taxation of recreational marijuana, which was approved by over 60% of voters. House Republicans won more votes than Democrats: Republicans won 50.1% of votes on the general ballot to the Democrats' 49.9%.

Controversies

Early call

Fox News called Arizona for Biden at 11:20 p.m. EST on November 3, election day, with 73% of projected vote counted. The Associated Press did so at 2:51 a.m. EST on November 4. Fox News received push-back from the Trump campaign as no other network called Arizona on election night. Fox News decision desk director Arnon Mishkin defended the Arizona call at 12:30 a.m., saying that Fox News was "four standard deviations from being wrong" and that Trump was "not going to be able to take over and win enough votes to eliminate that seven-point lead that [Biden] has". Biden and other Democratic candidates began election night with a wide lead in the state, and at the time Fox News called Arizona for Biden, he led by 210,259 votes (53.9% to 44.9%). The reporting in Arizona was the reverse of a 'red mirage' and 'blue shift' effect seen nationwide, where the counting of election day votes before early and absentee votes gave Republicans across the country an early lead. Votes cast on election day typically leaned heavily Republican while those cast early and absentee ballots leaned heavily Democratic, partially due to the skepticism of mail-in voting spread mostly by Trump and fellow Republicans. However, Arizona and several other Sun Belt states had the opposite effect. Early votes and absentee votes cast before the election were pre-counted and released shortly after 10:00 p.m. EST, when polls closed. Election day votes, as well as a few absentee votes, were released on election night and trickled in throughout the rest of the week. FiveThirtyEight correctly predicted that close races "might have to wait for those last few ballots before knowing who won". Despite Biden's lead dropping throughout the week, it became clear that Trump's margin among election day votes would not be enough to overtake Biden's lead: Trump needed 59% of the outstanding vote to win, but continuously won around only 53% of the votes released in several ballot dumps after election day.

On November 11, Decision Desk HQ, along with several other outlets, projected that Biden would carry the state. On November 12, ABC News, NBC News, CNN and The New York Times all projected Biden to carry the state shortly after 11:00 p.m. Eastern.

On November 24, 2020, Governor Doug Ducey acknowledged that Biden won the state.

Objection

On January 6, as a joint session of Congress began to certify the election for President-elect Joe Biden and Vice President-elect Kamala Harris, there was an objection to Arizona's 11 electoral votes, brought forward by Representative Paul Gosar of Arizona's 4th congressional district and Senator Ted Cruz of Texas, and signed by 67 other senators and representatives. Debates began over the objection in the U.S. Senate and House of Representatives, but were abruptly cut short after threats by pro-Trump demonstrators that escalated into a fullblown storming of the Capitol, forcing the building to be locked down and Congress to be evacuated. After the Capitol was secured at 5:40 p.m. and Congress reconvened, the objection failed 6–93 in the Senate, and 121–303 in the House. The riot reportedly dissuaded several Republican senators and representatives from objecting to the Electoral College results.

Kelli Ward (left), future Chair of the Arizona GOP, would ultimately vote to censure Doug Ducey (second from left) for his refusal to overturn the Arizona election results.

On January 24, 2021, the Arizona GOP voted to censure Cindy McCain, Jeff Flake, and Doug Ducey, all of whom vehemently denied conspiracy theories from the Trump campaign arguing that the results in Arizona were fraudulent and invalid. Between January 6 and January 20, the Arizona Secretary of State office reported that over 8,000 Republicans changed their party registration to Democrat, Libertarian, or unaffiliated, which was attributed to said actions by Trump and the Arizona GOP.

Lawsuits

Main article: Post-election lawsuits related to the 2020 U.S. presidential election from Arizona

Following the election, Donald Trump, the Arizona Republican Party, Republican National Committee, and several others filed lawsuits attempting to overturn the results of the election in Arizona, citing unsubstantiated claims of voter fraud.

Overvotes lawsuit

On November 7, 2020, the Trump campaign, the Republican National Committee, and the Arizona Republican Party filed a lawsuit against Secretary of State Katie Hobbs and Maricopa County Recorder Adrian Fontes that alleged that overvotes were "incorrectly rejected". Overvotes occur when a voter marks more than the options allowed in a given race, and stray markings can often be processed as overvotes by tabulation machines. The machines are programmed to alert voters of the overvote, allowing them to either request a new ballot or proceed with the original one. The lawsuit argued that those who chose to file their "original ballots are entitled to a manual inspection of their ballots later," and claimed that voters were urged to cast their original ballots by poll workers rather than request a new one. In total, 4,816 votes were deemed overvotes, which would be insufficient to overcome Biden's 10,457-vote advantage. A representative for Maricopa County stated that only "180 potential overvotes" were involved in the lawsuit, and that it would be "absurd" to assume all 180 were incorrectly counted. The Trump campaign requested that their evidence be kept secret from the public, but the judge refused to allow the secrecy. The Trump campaign also stated that they had video footage from within a polling area; however, such footage would be illegal if taken within 75 feet of a polling area with voters present. Thomas Liddy, a lawyer representing Maricopa County, deemed the lawsuit unnecessary, as if their claims were correct, both Biden and Trump votes would be equally affected, while Roopali Desai, an attorney representing the Secretary of State, argued the lawsuit attempted to "find a problem when one does not exist".

Mick West, a skeptical investigator and creator of the website Metabunk, cited how the percentage of votes deemed overvotes was lower or the same percentage as the last four elections, and a considerable decrease from 2016, when 21,785 overvotes (1.4%) were cast in the presidential election in Maricopa County.

On November 10, 2020, Associate Presiding Civil Judge Daniel Kiley accepted a request from Snell & Wilmer, the law firm which was representing the Trump campaign and its allies, to withdraw from the Arizona lawsuit. On November 11, 2020, Arizona Attorney General Mark Brnovich rejected Trump's voter fraud claim during an interview with Fox Business and stated that Biden would win the state of Arizona. On November 13, the Trump campaign dropped their lawsuit after it became evident that the number of votes potentially to be contested would not overcome Biden's margin of victory in the state.

Audits and recounts by election officials

By November 7, hand-count audits had been completed in Cochrise, Coconino, Grenlee, Maricopa, Mohave, Navajo, Pima, Pinal, Santa Cruz, and Yavapai counties in order to test the accuracy of the voting-tabulation equipment. Each of these county hand-count audits either found there to be no discrepancies, or found their count to be within the acceptable margins of error identified by state election law.

Maricopa County's November 4 hand-count audit had found no discrepancies. From November 7 through November 9, 2020, an additional 47,000 ballots (2% of election-day ballots plus 5,000 early voting ballots) were hand-recounted by teams appointed by the county's three local political parties and again found no discrepancies.

On February 23, 2021, the Republican Chairman of Maricopa County's Board of Supervisors announced that forensic audits of their vote tabulation equipment by two independent auditors, who were certified by the U.S. Election Assistance Commission, found no irregularities.

Audit ordered by Arizona Senate Republicans

Main article: 2021 Maricopa County presidential ballot audit

Origins

On March 31, 2021, the Arizona Senate Republican caucus hired four firms to examine the ballots in Maricopa County in the races for President and for the United States Senate, with a Florida-based company called Cyber Ninjas being the lead firm. Cyber Ninjas' owner, Doug Logan, is a Trump supporter and a proponent of Trump's false claims of voter fraud. The process involves an audit to search for evidence of fraud, and a hand recount of the 2.1 million ballots cast in Maricopa County. The hand recount is managed by Wake Technology Services, which reportedly had been hired for a previous audit in a rural Pennsylvania county by Trump attorney Sidney Powell, who has promoted numerous conspiracy theories about the election; the firm works primarily in the healthcare sector with little to no experience with elections.

The Arizona Republicans funded the effort by using $150,000 from the State Senate operating budget, but this money is acknowledged to be insufficient and the actual source of funding has not been declared. Patrick Byrne, the former CEO of Overstock.com and promoter of 2020 election conspiracy theories, donated one million dollars to the effort and created a website to raise further funds, which was promoted by former Trump national security advisor Michael Flynn. The fundraising was conducted through a 501(c)(4) organization, a tax code provision intended primarily for the promotion of social welfare. One America News personalities also created a dark money organization to raise funds, while providing extensive coverage of the audit that drew praise from Trump. CueCat inventor J. Hutton Pulitzer claims to have invented a system for detecting "kinematic markers" which is being used by Cyber Ninjas. Pulitzer is also said to be the originator of the claim that Chinese ballots with paper containing bamboo are part of the claimed fraud. Flynn and Byrne stated that, if they were proven wrong, they would publicly apologize that they "put this country through this."

Conduct and concerns

The audit began on April 22, and on the same day Arizona Senate Democrats filed a lawsuit to stop the audit. The next day Judge Christopher Coury agreed to suspend the audit for three days until the contractors can present documentation on how they will conduct the audit. The suspension was conditioned on the Arizona Senate Democrats posting a $1 million bond to cover the cost that the delay could cost the Arizona State Senate Republicans. But because the Arizona State Senate Democrats refused to post the bond, the suspension did not go into effect. By May 5 Arizona Senate Democrats reached a settlement with the Arizona Senate Republicans to allow independent elections experts to observe the audit. The agreement authorizes Secretary of State Katie Hobbs to file suit against Cyber Ninjas for breach of contract if the company does not live up to the agreement.

Former Arizona Secretary of State Ken Bennett, a Republican, had been designated as the State Senate's liaison to the audit. On May 5, 2021, Hobbs sent a letter to Bennett, detailing additional concerns with the way the audit was being conducted. Her letter cited the audit's disclosed procedures (departures from best practices for hand recounts) and the reports of the observers sent from the Secretary of State's office (including sloppy handling of ballots). A response from the audit's Twitter account asserted that Hobbs's allegations were "baseless claimes [sic]".

Also on May 5, the United States Department of Justice sent Karen Fann, president of the Arizona State Senate, a letter expressing concerns that the audit may violate federal laws. One concern is that the law requires election officials to maintain custody of all voting records for up to 22 months. Another concern is that the statement of work for Cyber Ninjas authorizes Cyber Ninjas to knock on voters' doors to ask them if they have voted in the 2020 elections, which may amount to voter intimidation and constitute a violation of the Voting Rights Act of 1965. After the Department of Justice threatened to sue over this plan, Cyber Ninjas agreed not to do it.

As part of the audit, auditors have been looking for secret watermarks, machine-markings, and bamboo fibers within the ballots. The testing for bamboo fibers was intended to prove a conspiracy theory that counterfeit ballots were shipped from South Korea after the elections. The audit was supposed to have concluded on May 14, but as of May 9, only 12% of the ballots were counted. The audit is being conducted at the main floor of the Arizona Veterans Memorial Coliseum, which was not available for this activity beyond the original target date. Consequently, the audit went on hiatus on May 14 and resumed on May 24.

The objectivity of the audit has been called into question due to the involvement of Logan. Additionally, Anthony Kern, a former Republican state lawmaker who was present at the 2021 storming of the United States Capitol, has been seen tallying votes. Kern, who was himself named on the ballots as a would-be Trump presidential elector as well as running for re-election to the Arizona House of Representatives, has since been removed from the group with access to the ballots. Former Arizona Secretary of State Ken Bennett, a Republican, is advising the audit. Hobbs, the current Secretary of State, has criticized Bennett's efforts, saying he needs to "either do it right, or don't do it at all."

The audit has produced division among Arizona Republicans. After initially supporting the audit, on May 9 Paul Boyer, a member of the Arizona State Senate Republican caucus, criticized the audit, saying "it makes us look like idiots." The Maricopa County Board of Supervisors, which is dominated by Republicans, also opposed the audit. On May 17, the board held a hearing and sent Fann a twelve-page letter to dispute her allegations of wrongdoing by county officials. Republican board chairman Jack Sellers stated that the allegations were actually due to the incompetence of the auditors and accused Fann of an "attempt at legitimatizing a grift disguised as an audit." Fann, however, continued to support the audit, and sent the Board of Supervisors a four-page letter stating that "serious issues" had arisen during the audit. Arizona Republican Party Chairwoman Kelli Ward released multiple videos about the audit, in which she criticized the Board of Supervisors and raised "the possibility of placing the validity of the entire 2020 election into question." A poll conducted at the end of March found that 78.3% of Arizona Republicans believed "that there was significant voter fraud in the 2020 United States Presidential Election which compromised the integrity of the election."

Fann made an allegation, later amplified by Trump in a May 15 post on his blog, asserting that Maricopa County election officials deleted the voting database after the election. Maricopa County Recorder Stephen Richer, a Republican who oversees elections, tweeted that Trump's post was "unhinged", noting he was looking at the database on his computer at that moment. Richer added, "We can't indulge these insane lies any longer." The auditors later acknowledged the database had not been deleted.

The Arizona Republic reported in May that because Senate Republicans had given private companies and individuals unfettered and unmonitored access to voting machines, the county might need to expend significant funds and time to ensure the equipment would meet federal, state and local requirements for certifying and protecting election equipment. The Republic reported the voting machines were worth $6 million. Hobbs, the Secretary of State, later informed the Board of Supervisors that election technology and security experts, including at the federal Cybersecurity and Infrastructure Security Agency, unanimously advised her that the machines should not be reused in future elections because no methods exist to adequately secure them.

A preliminary report on the results of the audit, made at the cost of some six million dollars raised from Trump supporters determined to overturn the election, found no evidence of fraud. Despite that, Trump continued to claim that there had been fraud in the tabulation of results and confirmation of the Biden win. The audit claimed to have found minor discrepancies in the original, state-certified count, that had actually widened Biden's margin by 360 votes.
