Yesterday, CNN decided to ask a doctor if Chris Christie was too fat. The doctor, who used to work at the White House, and helped Bill Clinton shed 30 pounds, did not mince words. “It’s almost a like a time bomb waiting to happen unless he addresses those issues before running for office,” said Connie Mariano. ”I’m worried about this man dying in office.”

Chris Christie, as is his wont, went on the offensive. He called her a “hack” and said she should “shut up.” Oh, it’s on. “I find it fascinating that a doctor in Arizona — who’s never met me, never examined me, never reviewed my medical history or records and knows nothing about my family history — could make a diagnosis from 2,400 miles away,” Christie said told Bloomberg.  “She must be a genius. She should probably be the surgeon general of the United States, I suspect.”

Responded Mariano, upon being dutifully contacted by a reporter for comment: “You don’t have to be a doctor to see that he is obese.” Also, she added, “I’m not a hack.”
