At this point it is way to early to tell what will happen in November, but I think things still lean in the Dems favor. On the Republican side you have a pack of candidates with no real front runner, and any one of them could get the nomination, but none of them appeal accross the board to all Republicans. On the Democratic side, you have two front runners, either one of which is likely to be energizing to the party. Many primary results show a lot more Dems turning out than Republicans, which I think points to a more energized party on the Democratic side.

I also think the big government and fiscal responsibility lines of attack are not going to work for Republicans at all. It's been a Republican president and a Republican congress that have expanded the government and expanded the deficit and debt these past 8 years.
