You’re assuming that Trump will run by attempting to gain the support of centrists.
Much more likely, IMO, is that he’ll go straight for the hard-core racist vote and rely on voter suppression and violence to keep the opposition from the polls.
The “Pledge allegiance to Trump” images weren’t accidental. He’s already locked up the KKK support; now he’s using the same sort of minimally-deniable dog whistle to bring in the overt neo-nazis.
