Rick Santorum is looking to Louisiana for a rebound as Republican voters go to the polls Saturday in the state's GOP primary.
The former Pennsylvania senator is expected to do well in the contest, just a handful of days after a decisive loss to front-runner Mitt Romney in Illinois on Tuesday.
A win over the former Massachusetts governor would serve as a reminder that Romney still struggles among the GOP's conservative faithful, especially in the South. Santorum beat Romney in primaries in Alabama and Mississippi earlier this month.
But Romney is far ahead of Santorum in the race for delegates to
the Republican National Convention, and he's been beating Santorum in big Midwestern states.
