MANCHESTER, N.H. — In late January, the New Hampshire Republican Party held a gathering that attracted GOP officials, volunteers, activists, and various other members of the party elite from across the state. At the time, Donald Trump led the Republican presidential race in New Hampshire by nearly 20 points, and had been on top of the polls since July.

What was extraordinary about the gathering was that I talked to a lot of people there, politically active Republicans, and most of them told me they personally didn’t know anyone who supported Trump. Asked about the Trump lead, one very well-connected New Hampshire Republican told me, “I don’t see it. I don’t feel it. I don’t hear it, and I spend part of every day with Republican voters.”
