The human race loves a demagogue. We always have.
Though, historically speaking, our support of demagogues has more often been because we enjoyed the show. Only occasionally do we actually carry through with the election and then only because there's an army backing them or the populace in question is extraordinarily disenfranchised.
I think Trump is a queer mix of both. He is speaking for an uneducated community that has become somewhat disenfranchised overall (the polarization of America, etc), but I predict that the bulk of his supporters are really just here for the show.
