It's now Scorched Earth. We're overtly seeing McSame play the nastiest cards he can make up. Both he and Sarah Palin are 100% attack, all blood.
I expect Obama can flip this easily. McSame is now completely predictable because he's using the Rove playbook we've seen in the last two Presidential elections.
[UPDATE] Glad to see Howard Wolfson is calling it as he sees it: OVER.
Perpetually fretting Democrats will not want to accept it. The campaigns themselves can't afford to believe it. Many journalists know it but can't say it. And there will certainly be some twists and turns along the way. But take it to a well capitalized bank: Bill Ayers isn't going to save John McCain. The race is over.
