Newt Gingrich is again the Republican presidential frontrunner. How exactly did that happen?

Jon Stewart on Monday practically lost his marbles over Newt Gingrich’s hypocrisy in a debate ahead of the South Carolina primary. Gingrich responded to a question about his infidelity by railing against negative media and CNN’s “despicable” question.

“You imagined your wife, while she was dealing with having MS, would be open to you having sex with another lady you’d already been having sex with for six fucking years!” Stewart said. “I think you’ve got a pretty good imagination dispicability-wise.”

So now the former Speaker of the House is running as an anti-establishment, Washington outsider. Huh?

“You are the Washington outsider,” Stewart said. “When Washington gets its prostate checked, it tickles you.”
