Like I've said before, all Obama needs is CO and NM.
NM - Bill Richardson is their governor (popular Democrat), VERY likely to go to Obama
CO - Democrats held their convention there, Obama has been leading this entire time, they hate McCain for trying to steal their water as a senator or some nonsense
Obama gets these two and it's all over. Nothing McCain does would even matter. He'd have to steal PA or MI, which is NOT going to happen. Just like Obama isn't going to steal VA or FL.
This is still Obama's race to lose, and we're not even two weeks out from the RNC. Obama has one way to go from here, up. This is how politics works, you don't blow your load all at once like McCain just did.
