We have two, the XXV Amendment and impeachment. They don't work when the allegedly sane officials who operate them are cowards.Isn't it high time a mechanism (short of assassination) was put in place to remove dangerous lunatics from public office?
I include the Democrats in the House of Representatives in that definition. The leading charge in their articles of impeachment was "abuse of power," which is neither a high crime nor a misdemeanor, and therefore not impeachable. They didn't have the backbone to call bribery bribery.
