* In an interesting twist in Florida politics, former Florida Gov. Charlie Crist hasn't just endorsed Sen. Bill Nelson's (D-Fla.) re-election, he's also helping the Democrat raise money.
* On a related note, while some polling shows Nelson with a comfortable lead, the latest PPP survey shows the incumbent's margin over Rep. Connie Mack IV (R) at just two points.
