In an official statement, Grover echoed Boehner. "[Americans for Tax Reform] opposes all tax increases on the American people," he said.
Any failure to extend or make permanent the tax cuts of 2001 and 2003, in whole or in part, would clearly increase taxes on the American people. In addition, the failure to extend the AMT patch would increase taxes. The outlines of the plans are deliberately hazy, but it appears that both Obama's Simpson-Bowles commission proposal and the Gang-of-Six proposal dramatically increase taxes on the American people.
It is a violation of the Taxpayer Protection Pledge to trade temporary tax reductions for permanent tax hikes.
And this is precisely what you'd expect of course -- the Republican party isn't going to break with decades of orthodoxy because of a few blase statements to reporters. Which is why there was always reason to doubt the significance of Norquist op-ed. But that still leaves open the question of, well, how exactly we avoid a debt default?
