I dont think so, I think it was only intended to remove criminals.
But... that being said, with popular opinion behind them there are plenty of things Bush had done that could be considered criminal!
No. Impeachement was considered by the founders to be a political tool to remove a president. Not just simply a tool to remove a criminal from the oval office. That's what all the consittutional scholars I've listened too say. The word "high crimes and misdemeanors" has a different meaning in 18th-century english, than it does in modern language.
