A few weeks ago, Mitt Romney said in a Republican presidential debate that he is opposed to letting ex-felons vote, if they had been convicted of a “violent” crime. Now, Ohio Attorney General Michael DeWine, who was once a U.S. Senator, has withdrawn his endorsement of Romney and is instead endorsing Rick Santorum, specifically over Romney’s position on voting rights for ex-felons. See this story. Thanks to Rick Hasen for the link.
