Lincoln, and Kennedy might have disagreed with him about who was "treated more negatively"; and Nixon still can claim the "witch hunt" crown - with Bill Clinton currently not far behind and "you lie! - non-American" Obama - perhaps in a distant third place (the Trump tried very hard to move Obama Up to first on that scorecard).
However The Trump "Keystone Kop" Team Behaviors may yet prove to eclipse anything raised  against Clinton and Obama . 
I wonder many parents this morning  have "becoming President" as a current aspiration for their kids?
