As Republicans prepare to pick their next presidential nominee, there's one primary that's already likely to get expensive and intense: Florida -- home to former governor Jeb Bush, who is likely to run, and Sen. Marco Rubio, who made his announcement in Miami.

That's why Scott Walker, the Wisconsin governor who has been riding high in early polls, said Tuesday that he might skip the Florida primary.

“If we chose to get in, I don’t think there’s a state out there that we wouldn’t play in," Walker, who has yet to get into the race, said on Laura Ingraham's radio show on Tuesday. "I mean, other than maybe Florida where Jeb Bush and Marco Rubio are, at least in some of the polls, essentially tied, and they’re going to eat up a good amount of that financial advantage that Gov. Bush is going to have. Remember [Florida Gov.] Rick Scott spent something like a 100 million dollars running for governor there last year."

Walker said that if he chooses to get into the race, he would first focus his time, energy and resources on the country's first three nominating contests in Iowa, New Hampshire and South Carolina.

In particular, Walker said he plans to make "a strong play in Iowa," although he declined to say if he would participate in the Iowa Republican Party's straw poll in early August. Bush recently announced that he's skipping the straw poll so that he can instead attend a conservative forum in Atlanta. Former Arkansas Gov. Mike Huckabee, winner of the 2008 Iowa caucus, is also skipping the straw poll this year.

Bush, Rubio and Walker are all expected to attend an economic growth summit that Scott is hosting in Orlando next Tuesday.
