Louisiana Republican primary

Louisiana's Republican elected officials are scrapping or delaying Florida travel plans for the GOP's national convention. Some who had arrived in Tampa quickly turned around and headed home to wait for Tropical Storm Isaac.

Gov. Bobby Jindal hasn't officially canceled his plans to speak at the convention, but says he won't leave Louisiana "as long as we're in harm's way."

Rick Santorum is leading in Republican presidential polls in Louisiana. But the candidate spent time countering missteps ahead of the Saturday primary.
