This isn’t the Left’s “base” any more, if it ever was. But more importantly, why would we want it to be?

It’s a shrinking share of the population. They voted for the candidate who promised them that only they matter.

What can the Left offer them that a) is different from what they’re already voting for, and b) won’t alienate the Left’s actual base: the coalition of everyone else in the country who isn’t a straight white Christian man but still believes in human rights and equality and freedom?

The “white working class” is a group of people with nothing to offer and to support them means to harm everyone else in the country for no benefit to anyone. And, importantly, they can’t be the “base” of both parties. Let’s not fight to find out how tiny a proportion of them might not actually be white nationalists.
