Santorum needed a big victory today in Louisiana, and he got it. The polls closed at 8:00 PM and the networks called the Pelican state for Santorum immediately. According to the exit polls Santorum won every demographic except those earning over 200k who went for Romney. Vote percentages look like they will be in the range of 46-28, with Romney taking the 28. As in Illinois, Gingrich was a non-factor. This race is supposed to be all over according to most pundits, but I guess someone neglected to tell the good voters of Louisiana.
Update I: At 99% of the vote counted, Santorum beating Romney by a whopping 22 points: 49-27.
