The Muslim ban, the David Duke denial, the “Mexican” judge flap, the draft dodger denigrating John McCain’s military service, the son of privilege attacking an immigrant Gold Star mother and the constant revisionism and lying about past political positions taken are but a few of the lowlights that have punctuated Donald Trump’s chaotic chase for the presidency. Any one of these offenses would have disqualified any other candidate for president. But the Republican nominee remained competitive against a historically weak Democratic nominee on the promise of bringing radical change and dramatic disruption to Washington.
