Voting by mail: Trump has been falsely suggesting that voting by mail is a “scam” and will lead to massive voting fraud — a charge he can now easily resurrect if he loses in November.

Reality check: People vote by mail all the time. About a quarter of all voters in 2018 cast their ballots by mail, according to the Election Assistance Commission.

Per election law expert Rick Hasen, the risk of fraud isn’t zero, but it’s small and easily managed.

After Trump threatened to withhold funds from Nevada for sending out mail voting ballots, its Republican secretary of state, Barbara Cegavske, pushed back in a statement: “For over a century, Nevadans, including members of the military, citizens residing outside the state, voters in designated mailing precincts, and voters requesting absentee ballots, have been voting by mail with no evidence of election fraud.”
