I don't mean this to be offensive, but serious. He must not be right in the head to write a "blog" post like he did:
"If Dean loses, will he quit?"
Which basically states his assertion that Dean will run as a third party candidate, unless he is bought off by the party.

He was corrected on this point by an e-mailer, who points out that Dean constantly states he will NOT run as an independent.
But Kaus has the balls to say, "Well, campaign promises are often broken."
I wrote him an e-mail, I encourage you to do the same.
