Bait-And-Switch Keeps Proles Voting Repub

“This theory of white working-class alienation from the Democratic Party derives from Thomas Frank’s compellingly argued 2004 book, What’s the Matter With Kansas? To Frank, the proletariat suffers from a form of “derangement” in believing that its woes derive from the decline of traditional values—patriotism, organized religion, self-reliance, the heterosexual two-parent nuclear family, etc.—when the true source of its troubles is a set of economic policies that favors the rich. Republicans have come to win blue-collar votes in elections by portraying Democratic tolerance of racial and cultural diversity as depravity—”abortion, amnesty, and acid,” in the famous slogan used against George McGovern in 1972. (This is not a new trick.) GOP officeholders typically set their conservative cultural agenda aside after the election is over to concentrate on cutting taxes, reducing regulation, busting unions, and so forth”/ Timothy Noah , Slate.
