Who Won the Republican Debate?

The Republican presidential circus traveled back through the looking glass on Thursday night into a world where candidates distinguish themselves over how to ensure Social Security's solvency and a competitive trade policy, rather than the size of their hands and other appendages.

The substance-heavy debate felt like a palette cleanser after a Jerry Springer-inflected clash last week that embarrassed the entire party. The most telling sign of the lowered temperature in Miami: frontrunner Donald Trump, who has remained a cartoonish provocateur even as he's pulled away from the field, turned in perhaps his tamest debate performance to date.

It could be the first signs of a prevent defense as Trump sees the nomination nearing his grasp. He made it roughly 100 minutes into the two-hour event before mentioning his poll numbers, surely a personal record in restraint. And in the concluding moments of the event, Trump even made a plea for party unity (“be smart and unify”), with the implicit message that at this point in the race, it amounts to an appeal for rallying around his candidacy.

"We’re all in this together. We’re going to come up with solutions. We’re going to find the answers to things," he said. "And so far I cannot believe how civil it’s been up here."

Then again, Trump will be Trump. He doubled down on his Wednesday comment to CNN that Islam -- all of it -- hates the United States. "There’s something going on that maybe you don’t know about, maybe a lot of other people don’t know about, but there’s tremendous hatred," he said. "And I will stick with exactly what I said to Anderson Cooper." He sidestepped an opportunity to condemn the violence that's become a hallmark of his campaign rallies. And he repeated his praise for Vladimir Putin as a "very strong leader for Russia" before attempting to qualify that, unbelievably, by adding, "strong doesn't mean good."

Trump is no master of policy nuance, and his flimsy grasp of the issues beyond anything that could fit on a bumper sticker showed through, clearly, again. But the measured tone of the debate also meant that Trump's remaining rivals for the nod avoided ganging up to attack him on his checkered history as a businessman and political freelancer. GOP establishment leaders are now frantically marshaling their donor class to fund attack ads highlighting that bio. Yet days before make-or-break primaries next Tuesday, the candidates who hope to benefit from that assault declined to use their last, best platform to echo the message. On that score alone, Trump can call the night a win.
