The rumblings have gotten louder, and the first news reports are in: Florida Gov. Charlie Crist is expected to announce that he will run for Senate as an independent. Surprise. 

Crist has told allies that he will leave the Republican primary, according to Fox News.  He has also informed several top fundraisers of his decision. 

Whether this means he'll run as an independent Republican or as a pure Republican-rejecting independent is yet to be determined.

Crist will appear on "This Week" with Jake Tapper and "Meet the Press" with David Gregory on Sunday, surely a sign that the man has something to say.

His consultants, led by pollster Glen Bolger, will likely resign immediately, leaving him, temporarily without a staff. But he has $7 million in the bank to build a new team. 

Crist trails Marco Rubio by over 20 percentage points in the GOP Senate primary, and it has consequently appeared nearly impossible that he would win the Republican nomination.
