David Weigel: Rand wondered aloud whether the showing in Michigan, coupled with the Reagan Presidential Library debate, represented the end of Donald Trump’s moment.

“I think Trump got almost no votes [he got 53; Rand got 174],” he said. “Every other campaign organized and tried to get supporters there. What we’re going to find is a reshuffling of the deck. To show how dramatically it’s reshuffled, you can look at polls that showed Walker at 22 percent a few months ago, and see that he’s at 0 percent today. Fiorina has greatly increased her numbers. As far as Trump goes, I think we’ll probably be done in the very near future with his domination of the polls. We can begin to rise.”
