It has a lot of political appeal.

That seems to be true. But if people want racism and giving up rule of law for expediency, what can Dems do? Turn to the dark side, too?

That's a goooood question. I don't have a good answer. If young men want to be racist, but no seen as racist - how do you appeal to that? The answer might be in finding out what else appeals to them that we can appeal to. Do they want houses or condos, a family, a decent job, but do they also see immigrants as taking jobs meant for them? Or lowering wages? Once that sets in, how do you counter it? Because it's likely to be a little bit true to a certain extent.

It looks likes they don't mind the Federal takeover of policing in the cities, and are happy with the idea of few immigrants making it across the border. Immigrants don't like that either. That border has been used as a cudgel since the beginning of the GFC,and probably prior, so it's a couple of decades now.
