Political hatred can damage the recipient, and the country, but backlash is common and the haters are usually damaged more. I once tried to come up with a list of Presidents who experienced unusual levels of vituperation from their opposition:
Granted that one was assasinated, another shot, and two impeached, but they were ALL re-elected. (However an historian friend of mind claims that the John Adams -- don't remember which one -- should be included, and neither Adams was reelected.)
John Q. Adams.
He was nearly impeached for having the audacity to want to build an observatory with government money.
Only one on your list was impeached (Clinton). Nixon would have been impeached, but he resigned to avoid it.
