What do they have that they have not already tried? They got nothin! That's why their claims get more and more ridiculous. I think that DeLay and Frist are not going to listen to their rantiings. The Rino's are cowards and will go with whomever they think will win.
Obviously, some of them think they see something in this Downing Street memo nonsense. They're going all out to force this thing onto the front pages without looking like they're doing so.
FWIW, I agree with you that "they got nothin'." But they're so consumed with hate for GWB, so caught up in their cozy little inside the Beltway left-wing echo chamber, that they're looking at this and seeing gold, while the rest of us see it's really a spray-painted turd. I think the public will have ZERO patience for a sham impeachment show, in the middle of a war. All they'll succeed in doing if they go forward wiith this is to push the President's approval ratings up well over 60 percent.
