Perceptions. trump never fought for ANYTHING except his own popularity and the profits he could make from holding office. trump said one honest thing in his '16 campaign, "I could shoot someone on 5th Ave and not lose a vote". His voters can't hear anything that doesn't prop up his faux persona, it's known as the con man effect. Admitting that they have been lied to from day one is too painful and so the con man (confidence) can return time after time to steal from them.
