Norquist has a lot of clout with in the GOP, but no where near enough for impeachment. First, the House would never go for it. If the impeachment fails, they look like assholes and it could hurt their re-election chances come 2014/2016. Second, the House would remember what happened last time they brought impeachment charges against the President; they failed and Clinton's approval rating went up considerably. Third, Congress looks at polls, and they know that
the majority of Americans want the Bush tax cuts repealed, so they would avoid such a politically risky fight. Finally, even if all the prior swing Norquist's way, he could
never get 67 Senators to agree to impeachment, let alone anything
