Mail-in voting has expanded substantially since 2000, accelerated by the COVID-19 pandemic. Eight states (CO, HI, NV, OR, UT, VT, WA, CA) and DC mail ballots to all registered voters. Most other states allow no-excuse absentee voting; a minority require an approved excuse.
Audits and post-election reviews of recent expansions have found ballot fraud rates near zero, though signature-match and chain-of-custody procedures vary widely. Election officials emphasize that mail voting is a complex logistical operation requiring funding, training, and clear standards.
The policy questions: should mail ballots be sent automatically to every registered voter, requested per election, or restricted to voters with a documented excuse? How should signature verification, drop boxes, and ballot curing work?
