Forgot to add, the Cavett ramble was in response to Chrissy's lament about the Sunnis (his constant harping of the last week).
Chrissy's theory is the Sunnis will try to secede and some kind of civil war will break out, and at the very least, their lack of participation in the vote (we shall see the real numbers of the Sunnis who did participate-reports are it may well have been much more than was expected) make the results invalid (the dem talking point).
I can't remember when Chris Matthews was right about anything. He is so over.
