There was an argument a time back that said the best way to kill the religious right’s political influence was to let it nominate a presidential candidate and then get creamed in the general election. That’d show that there’s no there there, and then the country could safely ignore their feet stomping. (Instead cosmopolitanism triumphed in the culture war, which was overall good, but has also lead to quite a bit of carrying-it-too-far-ness.)
Could the same thing happen with the segment of the low-education, nationalist, white working class that’s gotten its irrational and childish way with the (probable) nomination of Trump? His campaign looks headed for an epic defeat, and one utterly of its own making. His support comes largely from a shrinking demographic, one the country is slowly leaving behind, for reasons both bad and good.
I’m pessimistic, because this is politics and politics is always a source of pessimism. But the values that represent the core of Trump’s support represent a massive threat to America, to our way of life, our economic future, and the principles at the heart of the country’s founding. If Trump goes down as spectacularly as it appears likely he will, the best that could come of it would be the further marginalization of what increasingly looks like a rightly marginalized voice for a set of beliefs and values America would be far better off without.
