Voter fraud refers to illegal acts that interfere with the casting or counting of ballots, such as impersonating another voter, voting in multiple jurisdictions, or submitting falsified ballots. Academic studies and government reviews have generally found documented cases to be rare in U.S. elections.

In plain English

It means cheating in an election, like voting twice or pretending to be someone else. Studies have found proven cases are uncommon, though Americans disagree on how widespread it is.

Simple example
A 2016 review by The Washington Post and a Brennan Center analysis identified only a small number of confirmed in-person voter fraud cases out of more than 1 billion ballots cast in U.S. elections over more than a decade.
Why it matters
What the term actually changes.
Trust In Results

Beliefs about fraud shape whether voters accept election outcomes as legitimate, which affects participation and acceptance of peaceful transfers of power.

Policy Debates

Concerns about fraud drive debates over voter ID laws, mail-in ballot rules, and voter roll maintenance, while critics argue some measures can also limit access to voting.

How it works
The mechanics, in practice.
Detection Tools

States use signature verification, voter roll cross-checks, post-election audits, and bipartisan poll watchers to detect and deter illegal voting.

Legal Consequences

Suspected cases are referred to state attorneys general or federal prosecutors, and convictions can carry fines, imprisonment, and loss of voting rights.
