Rick Santorum will be the third presidential candidate to enjoy the endorsement of Ohio Attorney General and former U.S. Sen. Mike DeWine. The AG, who was the force behind Ohio’s participation in the states’ lawsuit to block Obamacare, initially supported former Minnesota Gov. Tim Pawlenty. When Pawlenty exited the race, DeWine transferred his support to Mitt Romney, whom Pawlenty also backed. Today, though, DeWine will reassign his endorsement yet again — this time to his former colleague in the Senate, Rick Santorum, according to Associated Press sources.
