We still have ten Republican candidates for president, and the ground is shifting. In this debate, sponsored by CNBC, Donald Trump "shared the oxygen with others," as Skimm put it. Two standout moments are when Jeb Bush and Marco Rubio sparred and when Ted Cruz accused the media of, well, being media. 

Bush criticized Rubio's work, saying he was treating his job "like a French work week." But Rubio fought back, leaving Bush unable to get another word in. According to Vox, Rubio clearly won the debate over Bush:

Bush was prepared. But Rubio was also prepared, and sharper. After cutting Bush to the quick - "Jeb, let me tell you, I don't remember you ever complaining about John McCain's vote record. The only reason you're doing it now is because we're running for the same position" - he denied that's what he'd done. "I can't campaign about the future of America or attacking anyone else on this stage," he said. Rubio became a happy conservative again. And that was that.

When Ted Cruz attacked the media for the questions asked, he got punished and lost his time. 

Discussion Starters:

• What's your view of the first video? Did Rubio do as well as Vox reported? 
• Do you agree with Cruz's assessment of the media? Was it fair that he lost time? Should the CNBC interviewers have handled this differently? If so, how?
