Immigrants — all immigrants — have always been the bulwark of the Democratic Party. For one thing, recent arrivals tend to be poor and in need of government assistance. Also, they’re coming from societies that are far more left-wing than our own. History shows that, rather than fleeing those policies, they bring their cultures with them. (Look at what New Yorkers did to Vermont.)

This is not a secret. For at least a century, there’s never been a period when a majority of immigrants weren’t Democrats.

At the current accelerated rate of immigration — 1.1 million new immigrants every year — Republicans will be a fringe party in about a decade.

Thanks to endless polling, we have a pretty good idea of what most immigrants believe.

According to a Harris poll, 81 percent of native-born citizens think the schools should teach students to be proud of being American. Only 50 percent of naturalized U.S. citizens do.

While 67 percent of native-born Americans believe our Constitution is a higher legal authority than international law, only 37 percent of naturalized citizens agree.

No wonder they vote 2-1 for the Democrats.
