The question is whether immigrants have different political positions than natives.
Latinos (and especially non-Cuban Latinos) absolutely have different political positions than average natives, and immigration consisting largely of them would in fact have the effect that Caplan denies.
However, I expect immigrants from any other country outside the Americas would be just as politically controversial if large numbers of them started arriving
I expect that if lots of them (or their descendants) voted for Republicans, they wouldn’t be politically controversial, because the Democrats and the left are spearheading the push for more immigration, and they would abruptly stop doing so. (This would not be compensated by Republicans pushing for them, because Republicans have no power to make such a push.)
