Santorum Wins in Louisiana

Rick Santorum won the Louisiana primary as expected to keep alive his faint hopes for the GOP nomination, reports AP. Santorum easily bested Mitt Romney to rebound from last week's loss in Illinois. But given that only 20 delegates were at stake, tonight's results won't do much to change his near-impossible delegate math. With 99% of precincts reporting, Santorum had 49%, ahead of Romney (27%), Newt Gingrich (16%), and Ron Paul (6%).

"We're still here. We're still fighting. We still believe, as this race really shows," Santorum told his supporters in Green Bay. Expect the calls for Gingrich to drop out to intensify, notes Politico: He won't win even one delegate because he failed to reach the necessary threshold of 25% of the popular vote.
