Democratic pollster Mark Penn is hosting a fundraiser this week for Charlie Crist, the Republican-turned-Independent governor running against Democratic Rep. Kendrick Meek for one of Florida's Senate seats. 

Penn's fundraiser is the latest piece of evidence that suggests Democrats are hedging their bets in the Florida Senate race. 

Meek trails real estate mogul Jeff Greene (D) in recent polls and may not make it through the Aug. 24 primary. And if Meek does, he faces an uphill battle against Republican Marco RubioMarco RubioTillerson met with top State official: report McCain ‘very concerned’ about Tillerson Top Dem: Don’t bring Tillerson floor vote if he doesn’t pass committee MORE and Crist.  

The Democrats' contingency plan seems to be to convince Crist to caucus with them if he wins the general.

Crist supported President Obama's stimulus plan, which led conservative Republicans to break with him in Florida. He decided to run as an Independent after it became clear he would not beat Rubio in the GOP primary.

According to an invitation to the fundraiser, Crist and his wife, Nancy Jacobson, will host the event at their Georgetown home on Wednesday.
