If you think about it, if the US was to impeach Bush --who is currently rather unpopular-- It would propel cheney (who can only be awesome with a shotgun) to the oval office. cheney is less popular than bush. So let's impeach both?

Nay, that would propel Nancy Pelosi into the whitehouse as the first female president and she's less popular and far less likable than bush, cheney, hilary clinton, and a molded turkey combined.

The impeachment process exists to legally remove a seated government official from power for criminal prosecution as to allow the government to continue operations without dividing said official's attention. It also helps with PR if you say Former-President instead of Current-President at the conviction and sentencing hearings.
