Huckabee looks to play kingmaker in Florida

In a departure from previous primary days this cycle, it's former Arkansas Gov. Mike Huckabee (R) who has the most on the line in Tuesday's Republican primaries in Florida.

Huckabee has endorsed in three competitive GOP primaries — he's backing Attorney General Bill McCollum in the primary for governor, Daniel Webster in the race for Rep. Alan Grayson's (D) seat and Karen Diebel in the primary to face Rep. Suzanne Kosmas (D).

In the governor's race, three potential 2012 hopefuls are behind McCollum — Huckabee, former Massachusetts Gov. Mitt Romney and former House Speaker Newt Gingrich. The primary between McCollum and Rick Scott was in a dead heat heading into Tuesday. 

But Huckabee is the only one who came to the state to rally for McCollum the weekend before the primary. He is also the only one who has waded into the most competitive congressional primaries in the state. Huckabee headlined a rally for congressional candidate Daniel Webster over the weekend. 

For the former governor, the endorsements in competitive congressional primaries mark a change in his political activity from earlier in the season. 

Along with a handful of endorsements in Florida, Huckabee offered last-minute backing to former Rep. Nathan Deal (R) in Georgia's gubernatorial runoff — Deal won — and released a new slate of endorsements in Iowa, the first state to hold a 2012 caucus.

It has increased speculation that Huckabee is mulling another presidential run in 2012.  

Elsewhere in Florida, the Republican primary for attorney general pits two potential GOP presidential contenders in 2012 against one another. 

Former House Speaker Newt Gingrich is backing former state Rep. Holly Benson, while former Alaska Gov. Sarah Palin is behind Pam Bondi. Both Gingrich and Palin recorded robocalls for their endorsed candidates.
