Winners and losers from the third Republican presidential debate

Ten Republican candidates spent two-plus hours trading rhetorical jabs in the third GOP presidential debate in Boulder, Colo. Marco Rubio won; Jeb Bush lost. Also, some others.
I separated the good from the bad below.

Winners

* Marco Rubio: The senator from Florida was good in the first two debates. He was outstanding in this one. The long-awaited showdown between Rubio and Bush wound up being a romp; Jeb tried to attack on Rubio's Senate attendance but got schooled by a very well-prepared Rubio. Rubio repeatedly took tough questions and turned them to his advantage, finding ways to tell his compelling personal story and steer the conversation toward what the GOP needs to do to beat Hillary Clinton. Rubio, as I've long noted, is the most naturally talented candidate in either party's field; he showed it tonight.
* Ted Cruz: Cruz had the single most memorable moment of the debate when, early on, he took on the CNBC moderators for the alleged "gotcha" questions they were asking. It drew a huge response in the debate hall and outside of it — and set the stage for a litany of attacks against the media from Cruz's rivals as the night wore on. Cruz, as he did in the first two debates, used his time wisely — driving home the message that he's the only guy with the backbone to stand up not just to Democrats but to leaders in his own party. Had Rubio not been so good, Cruz would be the story of the night.
* Chris Christie: For the second straight debate, Christie found ways to do more with less (time). His "Why the hell are we talking about fantasy sports" riff was outstanding and reinforced the idea of the New Jersey governor as a plain-spoken truth-teller. The question for Christie is whether it will make any difference; he continues to struggle to make up ground on the front-runners and is barely clinging to his spot on the debate stage.
* Donald Trump: This was a most un-Trump performance. With the exception of a smack-down of John Kasich in the early going, Trump was largely content to stay out of the fray and stick to his talking points when he did get a question. And, somewhat amazingly to me, he skated by without any real attacks by any of his rivals for the nomination. Yes, Trump has lost some momentum of late but didn't anyone notice he is still in first or second place in every single state and national poll? Hard to see him slipping from that perch as a result of tonight's proceedings.
* Lindsey Graham: For the second straight undercard debate, the senator from South Carolina was in a class of his own.  He was funny and knowledgeable. But, it was in the undercard debate.

Losers

* Jeb Bush: Oh, Jeb. This was a really bad night for someone who needed a good-to-really-good night. Bush tried to drop the opposition research book on Rubio's head in the early going but got beat by someone who is just better at this stuff. After that swing and miss, Bush seemed totally cowed for much of the next hour. Sure, he made one good joke about his fantasy football team. But one good joke in a two-plus hour debate does not a victory make. And as for his campaign's chagrin at CNBC for his lack of speaking time, that feels to me like a smokescreen designed to distract people from his poor performance. Prediction: The buzz about whether Jeb is up to this race, which was at a relatively low level before tonight, is going to start getting a lot louder.
* Ben Carson: The doctor's first three answers of the night were close to nonsensical. He repeatedly seemed surprised when called on and struggled to articulate his points or use facts to help bolster them. He seemed out of his depth. Now, Carson's appeal — and what has made him the race's front-runner of late — is that he sounds and acts nothing like a polished politician. So, I suppose, by that logic, Carson might have had a less-bad night than I think.

During the third GOP debate, candidates got feisty with the CNBC moderators. They took aim at the questions asked, at the "mainstream media" and at the moderators interrupting their answers. (Victoria M. Walker/The Washington Post)

* CNBC: Yes, some of the bashing of the network was simply politicians playing to the crowd. Republican voters think the media is biased, so when you as a candidate bash the media for being biased, you win. But, a lot of the questions the moderators asked seemed to be framed like this: "You said or did X controversial thing. Explain." I'm all for some of that — after all, politicians need to be accountable for their public statements — but it veered occasionally into "gotcha" territory.
