TIME – Republican state lawmakers are advancing a wave of new voting restrictions aimed at reversing the slew of pandemic-inspired election flexibilities, including expansions of mail voting, that most states adopted last year. But new evidence shows that those voting options likely led to significantly higher turnout among Americans with disabilities, a group that is equally as likely to vote Republican as Democrat.

Just 11% of voters with disabilities said they experienced difficulties in voting in 2020, down from 26% in 2012, according to a study on voting accessibility published Wednesday by the U.S. Election Assistance Commission (EAC). Among disabled voters who used mail ballots, just 5% reported experiencing difficulties, while 18% of disabled voters who opted for in-person voting encountered difficulties.

Those numbers mark a major change from previous election cycles, according to experts on political participation. “Anything that makes it easier, that provides more options to people with disabilities, is good for the turnout of people with disabilities,” says Douglas Kruse, a professor at Rutgers School of Management and Labor Relations who co-authored the EAC study.
