Rick Santorum is headed for a huge win in the Louisiana primary on Saturday, according to new numbers from Public Policy Polling. The survey shows that Santorum is beating Mitt Romney 42 percent to 28 percent, while Newt Gingrich is polling at 18 percent and Ron Paul at 8 percent. Romney also lost Alabama and Mississippi last week, and another big defeat could prolong the race and highlight Romney’s trouble with the South as conservative voters abandon Gingrich for Santorum.
