One prediction I have is that it will convince the easily dazzled young people who support him, as well as all those who consider themselves alienated and disaffected, that their vote really just doesn't matter, and that "the machine" will always win. (That there might be simply more of us than them will never occur to them.)
Anyway... this would be good. If the self-pitying grow too hopeless to vote, we'll have an easier time guiding the country back toward the right.
