Why have culture wars and identity politics been such a theme in this election?

Culture wars have always been a part of American politics, but it feels more blatant in this election. The McCain/Palin speeches seem devoted to championing the ideals of small town America – not quite sure what those values exactly are, but that’s neither here nor there — and bashing cities, intellectuals, and elites. There was almost no discussion of public policy whatsoever.

Contrast the McCain/Palin speeches with Reagan’s acceptance speech in 1980. Reagan’s speech has actual policy proposals in it.

So, back to my question. Why have culture wars and identity politics been such a theme in this election? Anyone? Anyone?
