Supposedly, the Obamessiah will try to make some comments blaming McCain for the economic mess, to keep McCain on the defensive. I tend to think that McCain will bring up the $105,000+ that Obama got from Fannie Mae and Freddie Mac quickly, and put the Obamessiah on his heels.
Hugh Hewitt has a thread on his blog which tries to establish an over/under for the times Obama says "Ummm . . ." or "You know," or 'Aaah," or "And." Don't quite know what has been established.
