While most registered voters across the country expect to cast their ballots in person this year, a quarter expect to vote by mail or absentee ballot (or have already done so). As in past election years, most of those who cast their ballots by mail or vote absentee express confidence in how mail and absentee balloting works. These voters are substantially more confident about this than voters who cast their ballots in person – a pattern that holds among voters who support both Republican and Democratic congressional candidates for the House of Representatives.
- 67% of voters who support the Republican House candidate in their district and plan to vote by mail, or already have, say they are confident that mail votes will be counted as intended.
- About half as many Republican candidate supporters who plan to vote in person (36%) say they are confident that mail ballots will be counted accurately.
- 78% of people who support their Democratic House candidate and have already voted by mail, or plan to, say they are confident that mail in votes will be counted as voters intend.
- A smaller majority (58%) of in-person Democratic voters say the same thing.

This is part of a larger Pew Research Center report on Americans views of election processes heading into the 2026 midterms, based on a survey of 5,062 adults, including 3,917 registered voters, conducted Sept. 28–Oct. 4, 2026. The survey was conducted prior to the Justice Department suing California on Oct. 15 to stop the state from counting the mail ballots of individuals who the Trump administration alleges are noncitizens.
Majorities are confident that mail ballots will arrive, and be returned, in time to be counted
An overwhelming majority of voters say that it is important that mail ballots be delivered with enough time to return them, and that it is important that the U.S. Postal Service return those ballots to election offices in time to be counted.
