The only reason that people don’t think that Donald Trump could be President is arrogance. We are no more special than those who had to endure racist and bigoted administrations for generations in sequence; and really, not that long ago. Further, that’s to whatever extent we think they ever disappeared.

People also arrogantly presume that others think as they do, but statistically many of your friends, neighbors and colleagues are Trump supporters – even here in the North East. 
You might even be one, and I accept that.
