Democratic state lawmakers are questioning a review by local county election boards into instances of voter suppression in Ohio during the 2012 presidential election.
Sen. Nina Turner and Rep. Kathleen Clyde said Wednesday that votes were suppressed when thousands of absentee and provisional ballots were rejected. They contend reports of long lines also discouraged voters.
But Ohio's Republican elections chief says bipartisan boards conducted an investigation into suppression. Secretary of State Jon Husted said in many cases, the Democrats' concerns stem from policy decisions that they don't like.
The investigation by Ohio's 88 county election boards found no documented cases of voter suppression and no referrals were made to law enforcement.
More than 5.6 million votes were cast last year in the presidential battleground state.
