There wasn’t one Republican presidential debate going on Thursday night in South Carolina, but rather two. And in that sense, the debate neatly and succinctly summarized this year’s unusual race.
The first debate was between the two unlikely front-runners, Donald Trump and Ted Cruz. After months of dancing around each other—and in some cases essentially supporting each other—in crystallizing antiestablishment anger, the two now know they are fishing from the same pond with less than three weeks to go before voting begins. And they conducted themselves accordingly.
The night’s second, parallel debate involved the other five aspirants on the stage— Marco Rubio, Jeb Bush, Ben Carson, Chris Christie and John Kasich—who seemed uncertain whether their mission was to go after the two top dogs or emerge from the rest of the pack as the alternative to them. By and large, they chose the latter course.
So Mr. Trump repeated, volubly and at some length, his assertion that Mr. Cruz, a Texas senator, might not be eligible to be president because he was born in Canada. Mr. Cruz responded by saying that his status under the Constitution isn’t in doubt, and charging that the businessman Mr. Trump fully agreed until he felt threatened by a Cruz rise in the polls.
“The Constitution hasn’t changed,” Mr. Cruz said. “But the poll numbers have.”
For his part, Mr. Cruz embraced anew his assertion that Mr. Trump embodies “New York values,” which, he said, are “socially liberal or pro-abortion or pro-gay marriage.” To a conservative debate audience in the conservative state of South Carolina, he added: “Not a lot of conservatives come out of Manhattan.”
