Is voter fraud a problem in the US?

Leans noSays it is contested

The evidence suggests voter fraud is rare but the issue is politically contentious, so it's worth breaking down what's actually known:

What research shows:

•Multiple studies, including conservative-leaning analyses, have found documented cases of voter fraud (like double voting, impersonation, or ineligible voting) are very rare relative to total votes cast
•A widely cited Brennan Center analysis found fraud rates around 0.0003% to 0.0025% in various studies
•Cases of prosecuted voter fraud are typically in the dozens or low hundreds nationally per election cycle, out of tens of millions of votes cast

What's more documented as an issue:

•Voter roll errors (outdated addresses, deceased voters not removed)
•Some registration irregularities
•Isolated cases of fraud that do get prosecuted, though rarely at scale
•Occasional issues with mail-in ballot chain of custody in specific instances

Where disagreement exists:

•Some argue that low prosecution rates reflect rare fraud; others argue detection systems are inadequate to catch fraud that occurs
•There's debate about how strict voter ID laws and other verification measures should be, balancing fraud prevention against ballot access
•Perceptions of fraud prevalence vary significantly by political affiliation, even when looking at similar underlying data

Bottom line: Large-scale, systematic voter fraud that could swing significant elections has not been substantiated by evidence from courts, audits, or investigations (including some conducted by Trump-appointed officials after 2020). Isolated individual cases do occur and get prosecuted. The debate is less about whether fraud exists at all and more about its scale, and what policies are proportionate responses.

If you're looking into a specific claim or election, I can try to help evaluate it if you share details.
