GOP Candidates Court Cajun Votes


Voters head to the polls in Louisiana today as former Pennsylvania Sen. Rick Santorum is poised to notch up another Deep South GOP primary win. Santorum continues to argue that he is the only Republican candidate who can offer voters a stark contrast with President Barack Obama.

But former Massachusetts Gov. Mitt Romney picked up a surprise endorsement this past week from former Florida Gov. Jeb Bush, in the wake of Romney's big win in the Illinois primary.

USA Today outlined five scenarios that could finally settle the GOP race:
1. Romney pulls off a clean win by the time the last primary states vote.
2. Superdelegates speed up the finish (most have stayed on the sidelines).
3. A contested convention results from Romney's inability to snag the necessary delegates.
4. If no candidate wins a majority in the first round of convention balloting, Santorum grabs the brass ring.
5. A brokered convention tosses out the candidates and drafts someone new.
