Ohio’s law allows the state to eliminate from voter rolls any registered voter who has not shown any “voting activity” in the last six years. The plaintiff, Larry Harmon, backed by the American Civil Liberties Union of Ohio and the think tank Demos, filed suit when he was found he was removed from the voting rolls for not attending the polls from 2008 to 2015. Ohio has purged more voters from its rolls than any other state — 2 million voters from 2011 to 2016, including 1.2 million for infrequent voting. An analysis from Reuters found that voters in Democratic-leaning areas were nearly twice as likely to be removed as those in Republican-leaning ones. The filing of the amicus brief is a direct reversal of the Obama administration’s position on the case.
