Do Open-Borders Candidates Turn off the Working Class?

In the 2000, 2004, and 2008 elections, there were warnings from the wrong side of the Right that open-borders candidates turned off the white working class. Now the Republicans finally nominated a candidate who didn't give nativists a “kick in the teeth.” It didn't do much good. Apparently, occupational or religious prejudice trumped racial prejudice.

Another point: Nativists often claim that open-borders candidates don't get Hispanic/Asian/whatever votes anyway. On the other hand, there was a large Democratic swing in the Hispanic/Asian/whatever vote in a year where everybody else was swinging Republican (and otherwise not showing up). That might have made a difference in Florida.

A third point: Open borders is the Right Thing To Do. We have no business depriving people of fundamental rights because of the accident of birth. (This also goes for the timing of birth as well as the place of birth.)
