A useful Newsweek piece details his temper and intransigence:
Republican state Rep. Jeremy Hutchinson says Huckabee has an explosive temper. He recalls one heated conversation with Huckabee about a health bill Hutchinson didn't want to support. Huckabee began screaming at him, and banged his fists on his desk so hard that "trinkets started falling off." ...
Jim Hendren, the state's Senate minority whip, says he gave up trying to debate issues with Huckabee. "It was like you became the enemy," he says. "There wasn't ever a negotiation. It was, 'It's going to be my way or else'."
