Who would be the strongest Dem Senate candidate?

[RBInMaine]

I really like Chellie and would ideally like to see her take it, but the fear is that too many men wouldn't vote for her, especially in the second district. (Too bad, but possibly very true.) Whereas Mike Michaud gets strong crossover support both by gender and party, and I think would be stronger in the first district than would Chellie in the second district. Again, I really really like Chellie, but I like Mike too, and I tend to honestly think that speaking electorally and demographically, he'd be the strongest statewide D candidate. The real fear here is though if King and/or Cutler get in splitting the moderate vote and throwing the race to a RePuke. That would be a real tradgedy.
