I was also struck, as in New Hampshire and Iowa, by the mood of this year’s rallies. Republican audiences this year want a restoration. America once had strong values, they believe, but we have gone astray. We’ve got to go back and rediscover what we had. Heads nod enthusiastically every time a candidate touches this theme.

I agree with the sentiment, but it makes for an incredibly backward-looking campaign. I sometimes wonder if the Republican Party has become the receding roar of white America as it pines for a way of life that will never return.
