To understand the changes taking place we need to look at them in more than one dimension, I don’t think left and right is enough. Red and blue is slightly better as many more colours can be described with various relations, but even that comes with more preconceptions than necessary.
I agree that Trumpism may not be that long lived. It is only one aspect of the “red religion", its purpose may simply be to tear down existing structures so its long term prospects may be unimportant. One positive impact of Trumps win is as a wake up call, and I don’t think those who were complacent or apathetic before will rally to the same old banners. Red and blue are both descriptions from the old order and there are plenty of network literate people on both sides, I look forward to seeing what new ideas come to life.
