Speaking of Doctor Dean, in Iowa today he blew his stack at a retiree who dared to criticize his mean-spirited negativity and seething persona: Iowa Voter Blasts Dean for Knocking Bush.

Dale Ungerer, a retiree from Hawkeye, Iowa, lectured Dean for nearly three minutes near the end of a forum aimed at winning voters for Iowa’s Jan. 19 caucuses.

Ungerer accused Dean and other Democratic presidential hopefuls of dividing the country by bashing Bush instead of outlining their own plans and showing respect for authority.

“Please tone down the garbage, the mean mouthing, the tearing down of your neighbor and being so pompous,” Ungerer told the former Vermont governor and Democratic front-runner. “You should help your neighbor and not tear him down.”

“George Bush is not my neighbor,” Dean replied.

“Yes, he is,” Ungerer said, to which Dean responded: “You sit down. You’ve had your say and now I’m going to have my say.”

But when Ungerer stood and tried to interrupt, Dean shouted: “You sit down. You had your say. Now I’m going to have my say.”

The crowd cheered and Ungerer sat.

“George Bush has done more to harm this county right here with unfunded mandates, standing up for corporations who take over the farmers’ land, making it impossible for middle class people to make a real living, sending our kids to Iraq without telling us the truth first about why they went,” Dean said.

“It’s not the time to put up any of this ‘love thy neighbor’ stuff … I love my neighbor, but I’ll tell you I want THAT neighbor back in Crawford, Texas where he belongs.”
