This is a very different question from asking whether we would be open to electing a certain type of president at a given point, because there are fundamentally so few presidents that some won't happen by luck. By your guesses, not only is Trump the last white straight Christian male president for a long time, but also each president is a new first. I don't see it going like that at all!
