Donna: Don't count on Obama losing in 2012. Unless the Republicans can come up with someone better than McCain or Palin, they're going to lose. Not that Obama is (or will be perceived as) that good but because there just aren't any charismatic Republicans out there. Palin? Palin is to the Democrats what Hillary was to the Republicans - they can't wait to rip her to shreds on the issues. Palin needs a lot more experience - and quitting her job as governor didn't help that.

Who do you see as a viable challenger in 2012?
