We have election to keep this kid of stupidity from happening, like it used to automatically happen in the monarchies or Europe!
It hasn't been a good thing since JQA, and even that is debatable since it was the election that brought the rise of the political party politics we see today.
You may argue that the GOP should have nominated John McCain or Alan Keyes in 2000 (Buchannan withdrew before the Iowa caucuses), but if he hadn't been president at 8:45am on September 11th, 2001, Al Gore would have been.
