Iowa: Braley, Vilsack and Culver have all been floated. But given that Branstad's approvals have looked a lot better from non-PPP sources, they may choose not to run.
Michigan: Hansen Clarke or Ving Bergano?
Ohio: Probably Cordray's seat as Mr X has suggested, but Strickland or Ryan could make a run as well. Or maybe even Kuninich.
Pennsylvania: People have floated Sestak, what about Holden or Altmire who have lost their House seats?
Wisconsin: Only Feingold could really test him here. I feel that Kind will run for Johnson's seat in 2016.
South Carolina: Sheheen? I don't see any other real candidates, lol.
Florida: Many people can run here and have a good chance of winning - Crist, Sink, Rich, maybe even DWS or Grayson
Texas: Maybe try Bill White or Chet Edwards?
Arizona: Goddard probably, though Giffords should run if she's mostly recovered.
Nebraska: Looks like Sheehy's running here.
Arkansas: Although the Democrats are struggling here, I think Ross and McDaniel are stronger candidates than anything the Republicans have to offer.
Maryland: Brown's probably favoured, although Franchot and Gansler could get the nomination as well. I don't see any Reps who could win here except maybe Steele or Erlich.
Massachusetts: Probably Murray's seat, though I can see Brown running if he loses to Warren.
Maine: Cutler can run as an Independent, or Pingree (both?) or Michaud can run as Dems.
Connecticut: Foley appears to be running again, though it'll probably be easier for the Reps if they run Simmons or Shays.
Hawaii: Djou?
Rhode Island: Don't know. Robatille will probably get the R nomination, though.
