I hope not as well.
But I think it is a distinct possibility. A possibility I have never entertained before either. The parties always claim that the other side is going to be out of power for decades or some other such nonsense every time they win. Demographic changes were never going to bring about democrats dreams of never ending power either. But Trump's supporters? I can see them following him off a political cliff. If 25% of republican support evaporates the republican party instantly becomes irrelevant.
I would see it as a good thing since the libertarian party would be the natural replacement but they have their head so far up their own ass they are never going to get more than single digit support. And sorry MAC, the forward party is not going to do any better
