No, that might be the question is Norquist wasn't lying and race-baiting... but he is.
See again the Norquist statement at #419:
"I never invoke the president or Karl Rove on this position - in anything."
From the Wall Street Journal, June 11th, 2003...
(I'm not a WSJ subscriber, btw, so I don't have access to their archive. I've linked to a reposting at FR, and a .pdf of Gaffney's.)
In 2002, Mr. Arian visited the Islamic Institute in Washington. Institute officials say his purpose was simply to drop off literature. Mr. Norquist adds that he himself has never worked with Mr. Arian and has met him only briefly at various events before Mr. Arian was indicted. Calling attention to Mr. Arian is unfair, he says. "Since I started working with Muslims, a handful of bigots have been trying to smear the president, Rove and me for working with them," he adds.

So, Norquist, in addition to his characteristic race-baiting, has been invoking both the President and Karl rove in this, both before and after he said he wasn't doing exactly that.
Norquist is repeatedly lying and race-baiting. If the truth were sufficient, why would he need to do that?
