White women and independents are flocking over to the McCain Palin ticket, and Joe Biden won't be helping by telling people that her being elected would be step backwards for women.
Barack Obama is in full defensive mode, not knowing how to react to the media that's suddenly being somewhat warm to the opponent, and realizing that a novice senator with no record, and a 35 year Washington insider aren't exactly "change agents".
The problem for him is his lack of a record is starting to show. While Palin can claim some legitimate (and some questionable) reform victories in Alaska, and McCain has a record of bucking his party, Obama's campaign folks claimed are grasping at straws for anything that might look like reform.
Sunday David Axelrod got caught with his pants down by Chris Wallace of Fox News, when he claimed that Obama's support of ethics reform and nuclear non-proliferation were items that "went against his party". Wallace was kind enough to point out to him that both of those items were passed by unanimous consent in the Senate, no roll call needed. That's not reform, that's following the herd.
While Obama has decided that Alaska keeping the "bridge to nowhere" money is bad; even if it's now being used for needed infrastructure improvements instead of the bridge; he voted for that money, twice.
My guess is that in the next 3 to 4 weeks we'll start seeing McCain ads about earmarks, that Obama will have to defend himself, and fellow Democrats against. Remember that in 2006 one of the hallmarks of the party taking over congress was that earmarks would get cut down.
Instead, last year Obama asked for $330 million, including money that went to the hospital his wife works at and companies represented by Joe Biden's lobbyist family members.
