AG DeWine Endorses Santorum

Ohio Attorney General Mike DeWine is backing Rick Santorum's presidential bid.      DeWine's about-face comes just 18 days before Ohio and nine other states host critical Super Tuesday contests.

DeWine served four terms in the House and two terms in the Senate before losing his re-election bid to Sherrod Brown in 2006.     He served as the chairman of Senator John McCain's 2008 presidential campaign in Ohio and won a close election for state attorney general in 2010.
