Are you crazy? Get the courts involved? Ad it stands now, Republicans do not have the votes in the Senate to get anything they want. But there is no way that Bush would be impeached in the House. The cowardly Senate might do wahatever the Washington Post told it to do, but the House is very firmly in controld the people-- right now, Republicans.
Get a court involved, and some appeals court might find that the Constitution requires that impeachment and conviction matters must be hadnled by federal courts in this special situation-- where a Republican President has a Republican Congress and some Democrat Members of Congress want to inititiate impeachment proceedings. To deprive them of the chance to bring down a Republican President would be to disenfranchise their Democrat constituents.
Or some such Barbra Streisand that will be dressed up in nice-sounding legal prose. Law professors will hail the sound decision.
