You read the title correctly! It's no joke, I did it myself. All you have to do is call 1-202-225-0100. This is a line to Nancy's office. All you have to say is, "I want to register my support for the impeachment of Bush & Cheney." They will say thank you and hang up. Trust me you'll feel a whole lot better. I sure did.
