Disagree about Hillary. There are a LOT of people who don't like her, (yes, I'm talking Democrats also, not just Republicans) and are really turned off by a return to office, via association, by Bill. We are SO much better off under Georgie Boy's tenure, aren't we?
Don't count out the mood in this country against Republicans at the moment. I'm not saying it will be easy, but I do believe Obama has a chance. Even though he's not from the deep South, FIL is a typical hardcore GOP can do no wrong conservative voter. He's admitted he thinks the war in Iraq is wrong, and he's voting for Obama.
We had Obama people canvassing here before the primary election, and it was a couple of die-hard ex-Marines who had been Republican their whole lives, and have switched parties and were trying to get people to register to vote also. The little old people next door to us were in our yard when they came by, and they both switched from (lifelong) Republicans to Democrats, and were voting for Obama as long as he won the nomination. (It wasn't decided yet, and they were NOT under any circumstances voting for Hillary.)
