No surprise here; they’d all vote Democrat.
Not that I’d recommend it, for obvious reasons, but wouldn’t it be interesting for a Republican to propose a bill that would provide amnesty for illegals, but not citizenship? In other words, they could stay here after paying some fines, etc., but they could never vote. I think that both the illegals and the legal, voting citizens of Mexican extraction would quickly learn that the only interest the democrats have in them is their vote. It’s a lesson that the Blacks should have learned, but sadly haven’t, over the past half-century.
