On Super Tuesday, two of the four states Trump lost were Oklahoma’s closed primary and Alaska’s closed caucus, both of which went to Ted Cruz, suggesting a potential weakness for the frontrunner. He’ll have to confront that today.

In Louisiana, voters had to be registered as Republicans by February 4. Two recent public polls in the state have Trump holding a decisive lead— a Trafalgar Group poll from early this week puts him at 44 percent, ahead of Cruz with 26 percent and Rubio with 15 percent.

But the closed primary, say Louisiana Republicans, gives Cruz a shot.

“I’m thinking advantage Trump, but given that this is only the second purely closed party primary, I’m thinking that Ted Cruz will be competitive to Trump,” says Louisiana Republican pollster John Couvillon.

Both Cruz and Trump held rallies in Louisiana on election eve. Rubio cancelled a scheduled event there.
