They may be poor now and they may be a burden on social services now (though I suspect they're heavy users of California's "safety net" simply because the net is there, and wouldn't be there otherwise), but immigrants by and large tend to be a very upwardly mobile demographic group. Members of my own family have married Spanish-speaking spouses from immigrant families, and the second generation in those families tends to be far more conservative than their white, native-born American counterparts.
I think the opposite is true in many cases, like why we lost the "Cuban vote" in Florida this year. The first generation of immigrants really did believe in traditional family values and despised socialism after they escaped a communist hell hole. But the third generation Cuban Americans don't care about grandpa's life and think socialism is kewl and gay marriage is hip.
Agree with both of you. We should have won OH, FL, VA, and CO but didn’t. Nonetheless, we can’t just double down on failure and just chase the white vote, something I’m seeing over and over in these threads. True, the white vote has some votes left on the table we didn’t get, as we didn’t lose WI and IA because of the non white vote. However, past a certain point, you are trying to get Unionists, Socialists, Communists, and the gay vote.
