Fox Business host Don Imus says you would have to be high to believe former House Speaker Newt Gingrich (R) can win against President Barack Obama in the general election.

On Monday, Imus told Mary Matalin, a former advisor to Vice President Dick Cheney, that she must be "smoking meth" if she thought Gingrich had shot a beating the current president.

"Can Newt Gingrich beat President Obama?" Imus asked Matalin.

"Yes, he can," Matalin stated without hesitation.

"Oh, well you're smoking meth or something," Imus declared. "You're insane."

The Fox Business host explained that people don't want to vote for somebody who "walked in and served divorce papers on their wife when she was lying in bed dying of cancer."

"You know that's a lie and you keep repeating it," Matalin objected. "His wife did not have cancer. It was a benign tumor and she wanted the divorce."

"Girl was in the bed sick!" Imus exclaimed. "He didn't know what she had. He's not a doctor, is he?"
