Is voter fraud a problem in the US?

No, voter fraud is not a significant or widespread problem in U.S. elections. It occurs at extremely low rates—typically measured in thousandths or hundred-thousandths of a percent of ballots cast—and there is no credible evidence that it has altered the outcome of any modern presidential or major federal election. Isolated cases happen and are prosecuted, but they do not indicate systemic issues.[1]

Key Evidence from Studies and Databases

Multiple independent analyses, government reviews, academic research, and even data from sources that highlight fraud cases converge on the same conclusion:

•Heritage Foundation Election Fraud Database (a conservative think tank’s compilation of “proven” cases ending in convictions, civil penalties, diversions, or official findings): It lists roughly 1,500–1,620 instances spanning decades (often back to the 1980s or earlier, across hundreds of millions to billions of votes). This is explicitly a non-comprehensive “sampling.” Analyses of this data show minuscule rates. For example:

•Arizona: 36 cases over 25 years and ~42.6 million ballots → ~0.0000845%.

•Pennsylvania: 39 cases over 30 years and >100 million votes.

•Similar tiny fractions in other swing states. No outcomes flipped by ballot fraud in these periods.[1]

•Brennan Center for Justice (reviewing 30+ studies): Voter impersonation rates of 0.0003%–0.0025%. An American is more likely to be struck by lightning than to impersonate a voter. Noncitizen voting is “vanishingly rare” (e.g., dozens of referrals or convictions amid tens of millions of votes in surveyed jurisdictions).[2]

•Other findings:

•A 2014 Washington Post investigation: 31 credible in-person impersonation cases out of >1 billion ballots (2000–2014).

•DOJ reviews of early 2000s elections: Fraud rates around 0.00000013%, with no coordinated efforts.

•Brookings Institution, Newsweek, BBC, and others using Heritage data or similar: Average of a handful of cases per tens of millions of votes (including mail-in). Post-2020 AP review of six swing states: <475 potential cases amid >25 million votes—far too few to affect results.[3]

•Mail-in/absentee fraud: Extremely rare (e.g., MIT and other studies find rates like 0.00006% or lower; no increased risk in all-mail states).

•Double voting, deceased voting, etc.: Often clerical errors or tiny numbers; studies find no widespread patterns.[4]

Fraud is more impactful (and sometimes more common relatively) in small local elections, where a few votes can matter and oversight may be lighter. National/presidential races have layered safeguards: bipartisan poll watchers/lawyers, signature verification, voter ID in many states, registration cross-checks (e.g., ERIC), audits, chain-of-custody rules, and prosecutions.

Recent Prosecutions

Individual cases continue to be found and charged (e.g., noncitizens voting, double voting, or using a deceased relative’s ballot). Recent DOJ announcements (2025–2026) have involved dozens to low hundreds of charges, often noncitizens falsely claiming citizenship or related offenses, spanning multiple elections and states. These remain a tiny fraction of total ballots (U.S. elections involve 150+ million votes in presidential years alone). Many involve mistakes rather than organized schemes, and there is no evidence of coordinated efforts sufficient to swing major races.[5]

Context and Caveats

•Detection vs. occurrence: Not every instance is caught, and some databases note potential issues with outdated rolls (dead voters still registered, dual-state registrations). However, extensive post-election audits, recounts, lawsuits (overwhelmingly dismissed for lack of evidence after 2020), and statistical analyses find no support for claims of “rampant” or outcome-changing fraud.

•Perceptions vs. reality: Polls show large partisan gaps (e.g., many Republicans view it as a major problem; few Democrats do), often driven by high-profile claims rather than data. Claims of millions of illegal votes have been repeatedly debunked.

•Safeguards matter: Fraud is rare because of existing laws, penalties (felonies with jail time), and processes. Improvements like better list maintenance or ID requirements are debated as policy, but the data do not show a crisis.

•Rare does not mean zero or unimportant. Every fraudulent vote undermines trust, which is why prosecution and prevention continue.

In short, U.S. elections are highly secure against fraud at scale. Isolated crimes occur and should be punished, but they do not constitute a systemic problem capable of deciding national outcomes. For the most current case details, see the Heritage map or official DOJ/election official reports.
