Can Trump win re-election if he stopped hateful speeches or Tweets?

Hasn't delivered his promises of industrialization. Jobs are still leaking and many issues remain. Most importantly, he failed to bring healthcare reform, he promised he would, "take care of everyone." That was a lie. Though he cut taxes for the rich, the benefit isn't clear for the working class. All they see him is playing golf and tweeting on the dime of the working man. He's almost 80, this dude is a racist to the bone. He won't change.
