Voter fraud is extremely rare in the United States. Fraud is more likely to occur in and affect the outcome of local elections, where the potential impact of a small number of votes can be greater. Some experts have said voter fraud can be difficult to prove or find, depending on the circumstances, although experts generally consider widespread cheating easy to detect. The term
fraud is often used to describe all illegal voting cases even where there was no intent. Cases of illegal voting are often accidental.
Nationwide databases In 2012,
News21, an
Arizona State University journalism project, published a database of 2,068 alleged voter fraud cases reported between 2000 and 2012. News21 gathered the information by sending public records requests to elections officials and prosecutors and reviewing court records and media reports and created the most comprehensive database to date of electoral fraud despite not being able to obtain data from all jurisdictions. The database also includes instances of
voter intimidation.
The Heritage Foundation, a conservative
think tank, publishes an incomplete database of voter fraud cases brought by prosecutors since 1979. As of November 2023, there were 1,465 proven cases of voter fraud listed in 44 years, an average of 33 cases per year. This represents a tiny fraction of total votes. In Texas, for example, Heritage found 103 cases of confirmed voter fraud between 2005 and 2022, in a period where 107 million ballots were cast, or 0.000096% of all ballots cast. Heritage has stated that the database is only a "sampling" and not comprehensive.
Voter impersonation Voter impersonation, or in-person voter fraud, occurs when someone votes in-person under the identity of someone else. It is extremely rare. Between 1978 and 2018, no elections were overturned by courts due to voter impersonation fraud.
Rutgers professor Lorraine Minnite has maintained that voter impersonation is illogical from the perspective of the perpetrator due to the high risk and limited upside of casting one vote.
University of Virginia law professor Michael D. Gilbert agreed with Minnite in 2014 that theory and evidence suggest voter impersonation "rarely occurs", though agreed with voter ID proponents that "the failure to observe fraud does not mean that no fraud takes place". Gilbert noted that it is difficult for someone to coordinate widespread voter impersonation to steal an election, as even if they paid people to vote in-person for their preferred candidate, the
secret ballot ensures they could not confirm whether these people voted the way they were paid to. Another 2012 study found no evidence that voter impersonation (in the form of people voting under the auspices of a dead voter) occurred in the 2006 Georgia general elections. In a 2013 study, the
New York City Department of Investigation (DOI) sent investigators to vote under the names of 63 ineligible voters, who were either deceased,
felons or had moved outside New York City. 61 of those investigators were allowed to illegally vote under their assumed identities. One of the two who was not allowed to vote was recognized by the mother of the felon they were impersonating, who worked at the polling place. In five instances, investigators in their 20s or 30s successfully posed as voters age 82 to 94. The DOI report stated that this result, while not large enough to be statistically significant, "indicates vulnerability in the system". In April 2014, Federal District Court Judge
Lynn Adelman ruled in
Frank v. Walker that Wisconsin's voter ID law was unconstitutional because "virtually no voter impersonation occurs in Wisconsin". A 2014
Election Law Journal study of the 2012 election found no evidence of widespread voter impersonation. In August 2014,
Loyola Law School professor
Justin Levitt reported in
The Washington Post 's
Wonkblog that he had identified only 31 credible cases of voter impersonation since 2000. The most serious incident identified involved as many as 24 people trying to vote under assumed names in
Brooklyn, which would still not have made a significant difference in most American elections.
Mail-in ballot fraud Multiple forms of voter fraud have been documented using mail-in or
absentee ballots, which include the requesting and submitting of absentee ballots on behalf of other voters;
ballot stuffing in absentee
drop boxes; coercion of voters, since the ballot is not always cast in secret; ballots being stolen from the mail and submitted; and collection of ballots by dishonest collectors who mark votes or fail to deliver ballots.
Ballot harvesting, or third parties collecting and delivering absentee ballots for voters, is also illegal or restricted in some states. While quite rare, experts say fraud occurs more often with mailed-in votes than with in-person voting. Between 1978 and 2018, at least fourteen elections were invalidated or overturned by courts due to absentee ballot fraud, twelve of which were at the local level (for such offices as
county clerk, sheriff, judge, and mayor). Postal ballots have been the source of "most significant vote-counting disputes in recent decades" according to
Edward Foley, director of the Election Law program at
Ohio State University. In 2012,
The New York Times wrote that according to election administrators, fraud in voting by mail was "far less common than innocent errors" but "vastly more prevalent" than in-person voting fraud.
University of Chicago political scientist Anthony Fowler said in 2020 that fraudulently voting on behalf of someone else, tampering with ballots, coercion or vote buying could all be easier with mail-in ballots, but that in practice "the risk of widespread fraud is probably very minimal, even with all-mail elections".
Loyola Marymount professor
Justin Levitt stated in 2020 that misconduct in mail voting is "meaningfully more prevalent" than with voting in person, but that misconduct "still amounts to only a tiny fraction" of mail ballots. An analysis by
News21 found 491 known cases of absentee ballot fraud between 2000 and 2012. In April 2020, a voter fraud study covering 20 years by the
Massachusetts Institute of Technology found the level of mail-in ballot fraud "exceedingly rare" since it occurs only in "0.00006 percent" of individual votes nationally, and, in one state, "0.000004 percent – about five times less likely than getting hit by lightning in the United States." A 2020
Washington Post analysis of data from three vote-by-mail states (
Colorado,
Oregon and
Washington), with help from the
Electronic Registration Information Center (ERIC), found that out of about 14.6 million mail votes cast in 2016 and 2018 officials had flagged just 372 possible cases of double voting or voting on behalf of deceased people. In many cases, ballot drop boxes are placed in locations where they can be monitored by security cameras or election staff.
Noncitizen voting Illegal voting by noncitizens occurs when noncitizens vote in elections they are not eligible to, such as
federal elections. It is
extremely rare. This is due in part to the more severe penalties associated with the practice including
deportation, up to five years of incarceration or fines, as well as the jeopardizing of
naturalization efforts. The federal form to register a voter requires a unique identification number such as a
Social Security or
driver's license number. New voters must check a box attesting that they are a citizen, though are not required to provide documentary proof of citizenship when registering. The extent to which states
verify citizenship of voters differs. Sometimes it also appears that more noncitizens are on voter rolls than there are because they became naturalized citizens but have not yet been back to the DMV to update their citizenship status in the DMV database. Studies of voter rolls have found very few noncitizen voters. As of July 2024,
the Heritage Foundation database includes only 24 noncitizen voting cases from between 2003 and 2023. and between 2017 and 2024, only three cases were referred for prosecution. In 2018,
CNN reported that in the past three years,
Kansas Secretary of State Kris Kobach had convicted three noncitizens of voting out of 1.8 million voters. A
Brennan Center for Justice study of 2016 data from 42 jurisdictions found an estimated 30 incidents of suspected noncitizen voting out of 23.5 million votes cast (or .0001% of votes). A review in Georgia found that no potential noncitizens had been allowed to register to vote between 1997 and 2022. At a May 8, 2024, press conference in which Johnson demanded that Congress pass an "election integrity" bill to stop noncitizens from voting, reporters pressed him on the lack of evidence. Johnson replied, "We all know intuitively that a lot of illegals are voting in federal elections, but it's not been something that is easily provable." Several Republican-led states have flagged and removed purported noncitizens from voter rolls ranging in the hundreds or thousands. Before the 2014 midterm elections in Florida, then-governor
Rick Scott announced a purge of 180,000 suspected foreign nationals from voter rolls, though only 85 names were removed and only one person was prosecuted.
A widely discredited 2014 estimate of noncitizen voting by
Jesse Richman and David Earnest was misused by Donald Trump and others to justify false claims it was widespread. 200 political scientists signed an open letter saying the study should not be cited or used in any debate on voter fraud. In 2020 and 2024, the libertarian
Cato Institute said that there was no detectable amount of noncitizen voting. Noncitizens who can vote in the few local elections where it is legal rarely cast ballots. Legal scholar
Richard Hasen, who had previously viewed noncitizen voting as a small problem, said in 2020 that claims of noncitizen voting "evaporated in the sunlight of public inspection and legal examination." He also said "spurious claims more likely serve as a pretext for passing laws aimed at making it harder for people likely to vote for Democrats to register and vote."
San Francisco State University professor and noncitizen voting expert Ron Hayduk referred to noncitizen voting as a "problem that doesn't exist".
Glenn Kessler in
The Washington Post stated there was "scattered evidence" of noncitizen voting and little to support the idea that it ever affected the outcome of a major election, but that the scarcity of evidence "does not necessarily prove that the phenomenon does not happen". He wrote that "if a noncitizen casts a ballot, there is no obvious victim to make a complaint and little public documentation to prove that a voter is not a citizen".
Double voting Double voting is when someone illegally votes twice, either in the same state or in different states during the same election cycle. It is considered extremely rare. When someone votes twice within the same state, it is often inadvertent, for example if a voter thinks their
absentee ballot will not be delivered in time. As of 2023, the only system that can detect double voting across states is the
Electronic Registration Information Center (ERIC), which close to half of states participate in. A 2008
Election Law Journal article found that a number of claims from the early 2000s purporting to have found double voters were due largely to the '
Birthday problem', or the statistical probability of people sharing the same name and birthday across multiple states. It noted that substantiated instances of double voting are 'notable mostly for their rarity.' The study found that many apparent double-voters were the result of incorrectly marking someone as having voted. The legal definition of double voting varies between states, but voting more than once in a given election is illegal under the
Voting Rights Act and comes with a fine of up to $10,000 and up to five years in prison.
Felony voting In the United States, depending on the state, a person may have their voting rights suspended or withdrawn due to the conviction of a criminal offense, usually a
felony. Felons who cast a ballot in those states often do not know that they were ineligible to vote. Out of
12 people on probation for a felony who were charged with illegal voting in
Alamance County, North Carolina in 2016, five stated in separate interviews with
The New York Times that they had thought they were allowed to vote. At least seven pled down to
misdemeanors.
The Guardian reported in 2024 that prosecuting voters who were ineligible due to a felony was the main type of prosecution pursued in
Florida. In 2022, Florida governor
Ron DeSantis arrested more than 20 people who were ineligible to vote related to a felony conviction, nearly all of whom were confused about their eligibility after having received voter registration cards from the state. Between 2000 and 2012, News21 found 393 cases of alleged voter registration fraud across 34 states, many of which were linked to third-party voter registration groups such as
ACORN. The registering of fake names, often motivated by quotas for third-party canvassers, has also been sometimes observed.
Outdated voter registration Outdated voter registration rolls occur when individuals who die, move away from a location or otherwise become ineligible to vote remain on voter rolls for a period afterwards. The phenomenon has not been linked to voter fraud despite allegations connecting the two. A 2012 report by the
Pew Center on the States based on data collected in 2008, found that over 1.8 million dead people were registered to vote nationwide and over 3 million voters were registered in multiple states. As of October 2024, Michigan had one of the most bloated voter rolls in the nation, with 500,000 more registered voters than citizens of voting age. This has not been connected to fraud, and is caused in part by federal laws restricting the removal of inactive voters. In 2020, the
Arizona Attorney General investigated 282 claims of dead people voting and found one which was substantiated. The same year, Republican legislators in Michigan found two dead voters in
Wayne County out of a list of 200 supposed cases. In a notable case in 2025, a
Los Angeles County man received a mail-in ballot for a woman who had died 31 years ago, though there was no evidence anyone had voted on her behalf.
Vote buying Vote buying is illegal in the United States at the federal level if money is promised to certain individuals to vote or register to vote, though at the state level, most states only criminalize paying people to vote. Promising cash payments to a large number of voters is legal. Courts have also historically considered providing free transport to voters legally permissible. While illegal vote buying has occurred relatively more often in certain areas such as
Appalachia, experts say it is rarely an issue in national-level races. Vote buying schemes affected at least six local elections between 2009 and 2012, four of which were in Appalachia. The legality of a
Cards Against Humanity program that would pay up to $100 to 2020 nonvoters who make a plan to vote in 2024 was similarly debated. A 2020 study in
Acta Politica found that around 25% of Americans would be willing to sell their vote for a minimum payment of $418. Democrats and liberal voters were more likely to sell, and the likelihood was not impacted by education or income levels.
Other types A type of fraud that sometimes occurs is falsification of signatures on
nominating petitions or
ballot initiatives. Experts say that as the cost of gathering paid signatures goes up, there is a greater incentive for this type of fraud. There is a variety of other types of election fraud, with varying prevalence, including: • Election workers changing or destroying ballots after they arrive. • Election workers marking ballots as void, so they appear as 'undercounts'. • Ballot stuffing, where the perpetrator will insert ballots pre-filled to a given candidate. • Helping people to fill out provisional ballots, then discarding those ballots. == Notable cases ==
