STATEMENTS THAT WOULD MAKE DONALD TRUMP'S POLL NUMBERS DROP

So far, none of the stupid shit this guy says is considered a 'gaffe' as far as his poll numbers are concerned. Is there something so stupid or outrageous that his audience would find revolting?
  1. "George Bush does not care about black people."
  2. "Homosexuality is a choice (in that gun ownership makes you gay.)"
  3. "Once I am president, the harvest of souls shall begin, per my contract with Satan"
  4. "I think we all need to acknowledge that white privilege exists"
    "Then we can begin to make America great again"
