House
On passage Passed by recorded vote: 240 - 189 (Roll no. 34).
Senate
Cloture on the measure invoked in Senate by Yea-Nay Vote. 68 - 32. Record Vote Number: 53.
Passed Senate without amendment by Yea-Nay Vote. 60 - 40. Record Vote Number: 54.
55.94% in House (not veto proof) 605 in Senate (barely veto proof, if no one changed their vote after a President of their party vetoed the bill, but that's speculation)
My bad, veto proof would be 67 votes (more than 2/3) not 60 votes or 60%. So the law was NOT passed by veto proof margins in either house of Congress. So President Bush could have killed this abomination dead as a doornail with a stroke of his veto pen...somebody did give him a veto pen, didn't they?
