Senior Romney adviser Ed Gillespie appeared on Chris Wallace’s show “Fox News Sunday” yesterday. Wallace, who usually tows the party line and has made has made his own viral internet appearances before when he tried to tango with Jon Stewart over entrenched partisanship, surprisingly came out swinging against the Romney campaign.

Wallace accused the Romney campaign of fuzzy math in refusing to explain how it will pay for its proposed 20% tax cut. He played the clip of Paul Ryan from last week’s debate in which he said they’d have to figure it out with Congress, and turned the question to Gillespie, who also couldn’t answer with specifics. He did say they’d pay for it by ending deductions, but only for the rich—they’ll leave them in place for the middle class. When Wallace pointed out there was no evidence that the math for this would work, Gillespie cited “studies,” which Wallace was quick to point out are “very questionable” and not independent. “You wouldn’t say that AEI is a conservative think tank?” Wallace asked. When Gillespie conceded Wallace said, “that doesn’t make it non-partisan.” “It does make it non-partisan,” Gillespie replied, trying the ol’ Jedi mind trick.

It was solid pursuit of reality by Wallace. Take a look below.
