Good essay. I don't know if you remember after Obama won in 2008 a bunch of democratic party apparatchiks came up with this idea of "the coalition of the ascendant" and that they pretty much had the government locked in for a generation, due to support that would never waver for them amongst immigrants, yuppies, tech bros, etc. They didn't need the working class anymore and the Republicans would be the minority party for many years.
Two years later the democrats were wiped out in the midterms.
