Candidates prepare for Louisiana primary
NBC NATIONAL NEWS — The Republican presidential race heads south again this weekend.
Tomorrow we'll see if Mitt Romney, who's scored victories everywhere else, can capture the Deep South.
The south has been a challenge for Romney.
He hasn't done well with conservative voters.
Now one of his rivals is suggesting if Romney wins, Republicans should turn their backs on the party.
It is day two of the "Etch-A-Sketch" campaign.
Mitt Romney's adviser used it to describe the election this fall.
Now Rick Santorum is telling Republicans four more years of President Obama is better than Mitt Romney.
"We might as well stay with what we have instead of taking a risk of what may be the Etch-A-Sketch candidate for the future," said Rick Santorum, Presidential Candidate.
Newt Gingrich disagrees.
If Romney is the nominee, he says, all Republicans should back him.
"There is no doubt in my mind that if the choice was Governor Romney or Barack Obama, we would have no choice. . . This guy's a disaster. He has no clue what he's doing. He's both radical and incompetent - the combination's almost unimaginable," proclaimed Newt Gingrich, Presidential Candidate.
Romney advisers are urging Santorum to get out of the race calling him President Obama's MVP.
Romney called Santorum's comment "disappointing."
He's behind Santorum by double digits, one day before Louisiana's primary.
But instead of playing catch up there, on Thursday Romney was courting lawmakers on Capitol Hill, and raising money, almost half a million dollars at a Washington fundraiser.
Outside that event, crowds chanted, "Shake it all you want, we'll remember in November."

All four candidates are in Louisiana today.
Twenty delegates are at stake in tomorrow's primary.
