Democrats will have to play identity politics (in a controlled way) because the Trump wing of the Republicans is the de facto White Man's Party. (Deliberate use of the word "Man.") In ope Primaries, pushing for the more radical Republican candidate is a good thing to do. In politics, as in athletics, "Nice guys finish last." Trump and his acolytes do not have to use the "N" word to get their message across. Even George Wallace, over 50 years ago, learned that. Trump gets a higher percentage of the "white" vote in the former Confederacy, but the message plays well nationally.
