Grover Norquist in the New York Times Week in Review on Sunday:
"There were no conservative grass-roots group saying, 'Invade Iraq,'" Mr. Norquist said. "If Bush changed the policy, you'd have four neocons whine and the rest of the movement would be fine."
Grover Norquist in the Washington Post, April 10, 2003:
"'The Democrats were on the wrong side of the Civil War, the Cold War and now the Iraq War,' said Grover Norquist, president of Americans for Tax Reform and an all-purpose chest-thumper on matters Right Wing. 'Their batting average on these things is right up there with France.'"
As far as I can tell from searching Nexis, Norquist didn't say anything negative about Iraq until October 24, 2004, when he was quoted as follows in a New York Times article exploring a hypothetical GOP response to Bush losing because of Iraq:
"Bush lost because of Iraq - O.K., but that doesn't suggest a change in policy because Iraq was not central to any part of the Republican party or its philosophy,'' said Grover Norquist, a leading conservative and the president of Americans for Tax Reform. "It was a judgment call. It may have been a good idea, it may have been a bad idea. So the Republican party will decide not to do more Iraqs. If you weren't the president, you weren't doing Iraqs anyway. The party will continue to be anti-tax and push for more. We will still be the deregulation party, and still the free trade party.''
