Indeed, but great-grandparent's assertions that said votes are reliably democratic are nonsense. Cuban-Americans tend to vote Republican (ask Marco Rubio), there are plenty of other Hispanics who vote Republican (ask Rafael "Ted" Cruz), and in fact, in the 2020 elections, Republicans have picked up votes in all sorts of immigrant communities (all the more remarkable, in my opinion, because it's hard to think how much
less welcoming the party could be to immigrants).
And some of the most rabid Trump supporters are recent immigrants (cf the Epoch Times' role in the last years, or the fact that one of the arrested Capitol rioters, Yevgenya Malimon, mother of an Oregon Republican party official, needed a Russian interpreter at her arraignment).
Think of other right wing voices in the US: Peter Thiel (first generation immigrant), Ron Unz (second generation), Roosh V (second generation).
Meanwhile, one of the key demographics for Biden's win in Arizona was high turnout among — Native Americans, the Final Boss of non-immigrants.
