Utah has the unusual distinction of being a deep-red state where voters enjoy automatic by-mail voting, but that will likely change in the next few years, in part thanks to the influence of conservative think tank the Heritage Foundation.

The state is poised to codify legislation that would get rid of the practice of automatically mailing ballots to all active, registered voters. The GOP-controlled legislature recently passed a bill that will phase out the state’s current automatic by-mail voting system by 2029 and also requires voters to list the last four digits of their state identification number with their return envelope beginning in 2026, according to the Utah News Dispatch. Those who opt in to voting by mail and include their state ID information will still be able to vote by mail.

The bill is a scaled back version of an earlier proposal that would have “drastically restricted voting by mail and required most Utahns to return their ballots in person at either a polling place or a drop box manned by at least two poll workers while showing their government-issued ID,” per the Utah News Dispatch.

Utah Republican Gov. Spencer Cox is expected to sign the legislation, The Washington Postreported Monday.

“We already have a good voting system and it’s not broken, so it doesn’t need to be fixed,” Melarie Wheat, the Utah advocacy director for Mormon Women for Ethical Government, told the Post. “There are going to be people who are expecting their vote-by-mail ballot and are not going to get it, who are going to say, ‘Well, it’s just not worth it and I don’t have time to go in at this point and vote in person.'”

Chris Diaz, director of legislative tracking for the Voting Rights Lab, told the outlet that “there’s never been a state that did this, in taking that step backwards after adopting universal mail voting.”

In 2012, Utah began allowing counties to run elections entirely by mail if they chose to do so, according to the outlet Bolts. Eventually, by 2018, about 90% of Utah voters cast ballots by mail, and in 2020 the state changed the default voting method for registered voters to vote by mail by automatically mailing a ballot to them (while still providing in-person voting options).

Researchers at Brigham Young University found that the shift to vote by mail led to a dramatic increase in voter participation in municipal elections.

Trump has repeatedly claimed that mail-in voting leads to fraud—despite having used the system himself in Florida. Research has found that incidences of fraud with mail-in ballots are exceedingly rare—and a recent legislative audit of Utah’s election system failed to find “significant fraud.”

State Rep. Jefferson Burton (R-64), the lawmaker who championed the bill, conceded to Bolts that the audit had not found widespread fraud in the state and that vote-by-mail has had a positive impact on turnout.

According to the outlet, when speaking about the bill Burton cited a scorecard maintained by the Heritage Foundation, the right-wing think tank that published the far-right policy blueprint Project 2025. The Election Integrity Scorecard gives Utah a relatively poor ranking—53 out of 100. Utah gets poor marks for its “absentee ballot management” and for currently not requiringa photo ID or a unique identifier when participating in vote by mail, among other criteria.
