She reads the documents she signs, she doesn't need Fox News and Breitbart to know what do and think, she doesn't know "good" white supremacists, she can get can get the minority vote out and never called majority black countries "shitholes". If she actually accepted to run against Trump, she would have no problems winning both the electoral college and popular vote! Not the greatest candidate, but at this point, anyone else would be an improvement.
The Obama years had constant growth and Trump is currently capitalising on Obama's programs. If taking credit for Obama's track record was not bad enough, he also lies about job his "record breaking" job numbers that's actually come short compared to Obama's last year.
Fear mongering and racism are not helpful in a modern world. And with "Shithole" Trump latest blunder, the little respect his country and the rest of the world had for him is pretty much gone. If he had any self-respect, he would resign before someone else takes the decision for him.
