It's funny. I would not ever want to paint Norquist as an ultra-powerful shot-caller. I just assume those are the guys who donate the money and the guys decide who gets the donations. When you think about it in those terms, he's perhaps more of a cultural artifact.

But wow, what an artifact! There has not been, to my knowledge, an instance of a newly elected US Senator publicly saying "signing this absurd thing is beneath the dignity of my office and of course I'm going to try to keep taxes low, the voters of xxx elected me because they know I'm a dedicated conservative, but it is impossible to guarantee that it will not be necessary to levy a new tax of some kind, so I am not going to promise that." Or something along those lines.

He doesn't get to decide who gets the donations, but he does get to administer the Kool-Aid, and it's powerful stuff.
