Uncommitted Iowa Senator responds to B. Clinton's alleged flare-up with superdelegates in California.
"I did say before he ought to chill out a little bit and from what I've seen I think he has, but again this recent thing in California, I don't know."
Also jokes that Clinton-supporter Carville is "the most uncontrollable person I've ever met."
Plus: Also called McCain's temper "scary" and questioned whether "flying off the handle" would affect his decision-making in the White House.
