Continuing his recent descent into supply-side boosterism, Rudy Giuliani told supporters listening to a National House Party Night webcast on Friday that tax cuts increase revenue (23:55 in the clip):

Remember, you collect more money with lower taxes than you do with higher taxes. I reduced the income tax in New York by twenty-four percent, and I was collecting forty percent more revenues from the lower tax than the higher tax.

As always, I will point out that nearly every economist disagrees with this claim. Even Bush administration economists have repeatedly contradicted President Bush on this point. But Giuliani, Mitt Romney, Fred Thompson, and John McCain are all touting it in an effort to win over economic conservatives. It’s a good thing supply-siders are “rather thin on the ground lately”!
