Republicans do love themselves some law and order. The reason I am worried about this one is that both parties covet their secret lists and neither cares all that much for civil liberties. Plus, American Populism is on the rise again, and that particular school of thought has always favored law and order over civil rights.
Whether we want to admit it or not, Trump’s instincts on this have a home. There’s plenty of people out there if you said, “Well, what if someone proposed a law that no one on the terrorist watch list could attend mosque?,” wouldn’t see any problem there. But I will say that at least the populists are consistent.
