Altho I thnk it's unlikely to happen, there have been some faint rumblings calling for impeachment.

If there's one thing we know about politicians of both parties, it's that they're like rats who desert the ship once it starts to sink.
And as Bush's approval ratings continue to drop and the mood of the American people hardens against him, you never know.
All it will take is one bombshell, and I certainly wouldn't be surprised if there's a bomb ticking away somewhere getting ready to explode in Bush's face.
