9. Florida (R-Rubio) - good chance he might run for President, and it is a swing state, but the Democrats have a weak bench in Florida.
Democrats can't knock out Rubio. They just can't. Not when your bench is a former governor and a lifelong Republican-turned-Independent (turned-Democrat?) and another former governor who's 75 and has been out of office for several years (Crist & Graham, respectively). The Democrats don't really have anyone else who can win statewide; Aronberg, Gelber, and Sink all lost statewide races, and Wasserman-Schultz can win South Florida but not Central/North. Maybe Rod Smith could run, or Bill Nelson if he loses 2012, but other than those, or maybe somebody like State Sen. Jeremy Ring or Nan Rich (Senate Minority Leader) in a long-shot bid, but generally, Rubio looks like he's staying.
