Twenty of Louisiana's delegates to the Republican National Convention in August are up for grabs in the state's presidential primary election Saturday, with candidates Mitt Romney, Rick Santorum, Newt Gingrich, and Ron Paul all eager to add the state's offerings to their tally.

But, according to Louisiana GOP Chairman Roger Villere, something more important than delegates is at stake in the primary: perception of momentum.

Romney, the former governor of Massachusetts, continues to blaze ahead in the overall race, with almost twice as many delegates as the candidate with the next highest tally, Santorum, the former U.S. senator from Pennsylvania. Yet, despite his advances, Romney still has yet to win any state in the South other than Florida, and he has yet to win a single state in what is considered the Deep South, a core area of the GOP base.

Recent polls indicate Santorum has a 13 percentage-point lead in Louisiana, with 40.7 percent support compared with Romney's 27.7 percent. Gingrich, the former speaker of the U.S. House of Representatives from Georgia, is third with 18.3 percent, and Paul, the U.S. representative from Texas, is fourth with 5.3 percent.

Romney's shut-out in the Deep South, Alexander Burns wrote for Politico this week. But if Santorum is to hold his momentum as the man who can not only not challenge but actually surpass Romney, he will need to make his victory in Louisiana a big one, proving he is the uncontested favorite of the party's base.

Meanwhile, Gingrich, who at one time expected to be Romney's main threat in the South, has so far won only South Carolina and Georgia, the latter the state where he served as a member of the House for 20 years. [If Gingrich can't] do well in Louisiana, then it's pretty much finished, Ed Chervenak, an assistant professor of political science at the University of New Orleans, told USA Today.

Paul, who took a temporary break from the campaign trail after the Illinois primary election, has spent some time in Louisiana, but he is focusing his attention on future contests in the District of Columbia, Maryland, and Wisconsin.
