Bill Clinton was a sleaze, but that is not grounds for impeachment. His voters knew that and voted for him anyways. It was the perjury - lying under oath on a topic that the judge had specifically ruled was germane to the case. That was one of the most serious non-violent felonies in existence. Clinton should have been removed from office for that major crime, not for one of his many "dalliances".
I like the idea of construing the Constitution so that impeachment is strictly reserved for “Treason, Bribery, or other high Crimes and Misdemeanors”.
