"No, you tell us the difference!" he barked.

"I'm not on your show, I'm just answering your question," she responded.

"Please come on my show," he said.

She then answered the Iraq question by returning to her stump speech message--troops out in 60 days and then bring the rest home in increments.

Did that satisfy the notoriously emotional Mr. Matthews?

I changed the subject and asked Mr. Matthews what he thought about Charlie Gibson last night as moderator of the debate; after all, Mr. Matthews has done it before.

"You can figure out the difference," he said.
