Is voter fraud a problem in the US?

I will examine this question using data from official sources, academic studies, and nonpartisan analyses rather than partisan claims.I have enough data for a balanced, evidence-based answer. Gathering a couple more precise details if needed.No, voter fraud is not a significant problem in the United States. It occurs, is illegal, and is prosecuted when detected, but extensive data from multiple sources—including conservative trackers, academic studies, government investigations, and nonpartisan analyses—consistently show it is extremely rare and has not altered the outcomes of modern federal (or most significant state) elections.[1]

Scale of Documented Fraud

The Heritage Foundation (a conservative organization) maintains the most prominent public database of “proven” election fraud cases (criminal convictions, judicial findings, civil penalties, overturned results, etc.). As of late 2025, it lists roughly 1,500–1,620 cases spanning primarily from the 1980s to the present (a “sampling,” not claimed to be exhaustive).[2]

•These cases cover decades during which hundreds of millions to over 2 billion ballots were cast in federal elections alone (presidential elections since 2000 have totaled well over 1 billion votes when including midterms and accounting for total ballots).[3]

•Resulting rates are vanishingly small: analyses using Heritage data put fraud at roughly 0.000065% to 0.000116% of ballots (on the order of a few cases per 10 million votes, or lower).[3]

•State examples: Arizona (~25 years, 36+ elections, ~42.6 million ballots) had ~36 cases (~0.0000845%); Pennsylvania (~30 years, 32 elections, >100 million ballots) had ~39 cases. No outcomes were altered by the fraud in these datasets.[1]

A separate national investigation identified 513 proven cases since 2016 amid >685 million votes cast. Only a tiny fraction (around 15) led to overturned results or new elections—almost all in smaller local or state races.[4]

Types of Fraud and Specific Findings

•In-person impersonation (the type often cited to justify strict voter ID): Extremely rare. One comprehensive review found 31 credible incidents out of more than 1 billion ballots cast (2000–2014). It is often described as rarer than being struck by lightning.[5]

•Mail/absentee ballot fraud: Also rare. A Brookings analysis of Heritage data for recent general elections (2016–2022) found an average rate of about 0.000043% of mail ballots (~4 cases per 10 million mail votes). Universal vote-by-mail systems show particularly low rates relative to other mail systems.[6]

•Noncitizen voting: Vanishingly rare. Brennan Center surveys of election officials overseeing tens of millions of votes found only dozens of suspected incidents (e.g., ~30 referred out of 23.5 million votes in 2016 jurisdictions, or 0.0001%). Heritage data and federal prosecutions similarly show tiny numbers over decades (dozens of cases, often involving lawful permanent residents who mistakenly registered). Recent DOJ efforts have charged dozens of noncitizens, but these remain negligible against total turnout.[7]

•Other (double voting, false registration, vote buying): Mostly isolated individual acts or small local schemes, not coordinated large-scale efforts capable of swinging major races. Post-2020 AP review of battleground states found fewer than 475 potential cases out of >25 million votes—orders of magnitude too few to affect results.[8]

Consensus from Research and Officials

Academic studies, the Brennan Center for Justice, Brookings Institution, MIT Election Data + Science Lab, NPR summaries of experts, Associated Press investigations, and others reach the same conclusion: documented voter fraud is “infinitesimally rare” and “almost never occurs on a scale that would affect an election outcome.”[8]

•Even aggressive DOJ efforts (under multiple administrations) yield low prosecution numbers relative to votes cast. Historical Bush-era initiatives found very few cases of the types often alleged. Recent increased focus has produced arrests/charges in the low hundreds at most over multi-year periods—still tiny fractions.

•Audits, recounts, court reviews, and Trump’s own Attorney General William Barr after 2020 found no fraud on a scale that could change outcomes.

•Safeguards include decentralized administration (thousands of jurisdictions), voter list maintenance, signature verification, ID requirements in many states, bipartisan observation, risk-limiting audits, and cross-checks with other databases. Errors (clerical, matching false positives) are far more common than intentional fraud and are usually corrected.

Fraud has occasionally affected very close local elections (e.g., some city council or mayoral races overturned due to absentee ballot schemes or vote buying), and any instance warrants investigation and prosecution. The Heritage database and others exist precisely to document vulnerabilities and cases. However, there is no credible evidence of systemic, widespread, or outcome-determinative fraud in contemporary U.S. national or most statewide elections. Claims of millions of illegal votes have been repeatedly debunked by data, courts, and officials across the political spectrum.

In short, while perfect integrity requires ongoing vigilance, list maintenance, and enforcement, the data show voter fraud is not a meaningful threat to the integrity or results of U.S. elections. Other issues (administration logistics, cybersecurity threats, disinformation, access barriers, or rare foreign interference attempts) receive more substantive attention from election experts.
