Mitt Romney surrogate Ed Gillespie was batted around by the unlikely source of Chris Wallace yesterday, when discussing the Romney tax plan. The talking point the Romney team has been throwing around is that “six studies” validate the claim that you can lower tax rates by 20%, remain revenue neutral, and not lower the share of the tax burden on the rich. “Share of the tax burden” is a weasel phrase that has more to do with the overall share of compensation going to the rich, but in some contexts Romney has said that he wouldn’t lower taxes for the rich, so we can read it that way.

This is all mathematically impossible, actual “studies” prove. But Gillespie and the surrogates have relied on the big-sounding “six studies” for their proof.
