Trump has never held elective office, but he is a career politician.
People are waking up to the fact that Trump is part of the Establishment Left.
He said, "I was part of the Establishment." And he has held every Leftist position at one time or other.
So there's that.
But what seems to have finally turned people off is his incessant whining.
