Santorum may win primary but lose Republican race
Former Pennsylvania Senator Rick Santorum looks likely to win the Louisiana primary, racking up another victory in the Republican race to challenge President Barack Obama.
A win by Santorum would serve as a reminder that Romney still struggles among the Republican party's conservative faithful, especially in the South. Santorum beat front-runner and former Massachusetts Gov. Mitt Romney in primaries in Alabama and Mississippi earlier this month. (AP)
