To me, those actions of his were all red flags.
The TV host was elected to the White House, supported by citizens who held up signs reading "Time To Take Our Country Back."
This weekend, white nationalists marched in Charlottesville, Virginia. One anti-nationalist reportedly was killed. There's video of some marching and shouting "Heil, Trump!" David Duke, a nationally known former KKK leader, attended the Charlottesville march and, on camera, said "We are determined to take our country back. We're going to fulfill the promises of Donald Trump..."
We saw Nazi flags in America. Just like the one Baron von Trapp tears down and rips up in Rodgers & Hammerstein's THE SOUND OF MUSIC.
