Wouldn't that impeach the 60 senators and the (however many) Reps in the House who signed it? I can't see them voting to impeach Bush on something that they sent him in the first place. Or, even more laughably, voting to impeach themselves, one by one, until only the 'nay' voters are left in both houses of Congress. Hmm, maybe that's a good thing.
