Sorry to butt in here, but I'm an Australian, a little out of the political loop here. You say "But Tom Delay is not going to be impeaching any judges, no matter his swagger".
Would you care to extend your comment to explain to an aussie why you sound so certain of that?
The majority of Republicans felt they were burned by passing federal legislation to give the de novo review. The American people, in every poll taken since the vote, opposed it.
I doubt DeLay has more than 100 votes in the GOP House for going after these judges. Without the votes, it's not going to happen.
That's to say nothing of the Senate, where any impeachments would be dead on arrival.
