In this video, Ralph Nader tells a group about how one congressman explained that part of the reason he won't vote for impeachment is that Bush will, in response, attack Iran, call for Martial law, and cancel the 2008 elections.
As Nader says, If the congressman is right, things are a lot worse, and if he's wrong, he's really paranoid and we don't have a healthy opposition party.
Ralph Nader is not a nut, not a fringey extremist. Watch the video. It's short and shocking.
