Rather, I’d say there are many immigrant groups with culturally conservative values (think Hispanic Catholics, BJP-aligned Indian immigrants, conservative Muslims, etc.) as well as certain more religious and patriarchal Black communities, that have a lot in common with the Republicans on social issues, and might be willing to overlook their racism if they find the Democrats’ stance on those issues unacceptable. Think also of expat communities that came to America on the heels of Communist revolutions in their home countries and have a reflexive hatred of even vaguely left-ish politics.
In a sick way, we’re lucky that the GOP’s embrace of racial hatred pushes as many people away as it does, because if they’d let that go they’d have a much broader base amongst minorities.
