Santorum Sweeps Louisiana

The GOP primary isn't over just yet. Rick Santorum cruised to an easy victory in Louisiana, winning twice as many votes as presumptive frontrunner Mitt Romney. Santorum took 49 percent to Romney's 26 percent, while Gingrich placed a distant third with 15 percent. Though the conventional wisdom says the win won't help Santorum much, the former senator seemed to expand his appeal, winning majorities of voters who only consider themselves moderately conservative and who think the economy is the most important issue in the election.
