It seems every time McCain reaches back across the aisle and tries to move to the moderate-left, he loses a few more points in the polls.
The Palin effect is probably over. She might help the ticket gain a few points in the debate tonight. But, even if she doesn, McCain will lose them during the month, as he continues to be the same ole McCain.
If she uncorks one more Miss Teen South Carolina state-of-consciousness ramble (that will be replayed ad nauseam by the talking head shows and late-night comics), it's all over.
