Trumpism without racism?

Donald Trump finished second in Iowa; he retains a big lead in New Hampshire. Whatever else one can say about his once-unthinkable play for the GOP nomination for president, it has forced people to reassess our politics in startling, far-reaching ways.

In every horse-race campaign moment and every polling fluctuation, we looked for confirmation of what we thought we knew: Trump was a celebrity-powered novelty, a charlatan fated to exposure, a niche candidate for the hardest-right voters, or an enthusiasm of resurgent white nationalism. 

None of these theories was entirely wrong, but none was remotely right enough.
