This quote is quite something:
“There's no evidence whatsoever that the Bush tax cuts actually diminished revenue. They increased revenue, because of the vibrancy of these tax cuts in the economy. So I think what Senator Kyl was expressing was the view of virtually every Republican on that subject.”
Some minor crank? Nah. Just the senate Minority Leader. Bruce Bartlett notes that even Bush-Cheney officials refused to claim as such; and the empirical evidence simply isn't there. But we are not talking about reality-based conservatism here; we are talking doctrine.
