Washington Post, via Jonathan Chait:
[According] to [Grover] Norquist’s interpretation of the Americans for Tax Reform pledge, lawmakers have the technical leeway to bring in as much as $4 trillion in new tax revenue — the cost of extending President George W. Bush’s tax cuts for another decade — without being accused of breaking their promise. “Not continuing a tax cut is not technically a tax increase,” Mr. Norquist told us. So it doesn’t violate the pledge? “We wouldn’t hold it that way,” he said.
Chait responds: “It’s pretty strange, isn’t it? Apparently Norquist interprets his pledge in some ultra-literal way that precludes it, in the case, from fulfilling its primary purpose. On the other hand, a plan to pass a one-dollar tax hike while cutting federal spending in half would violate the pledge.”
