Ramaswamy came out hitting the other candidates, saying he's the only one who hasn't been bought and sold. When it came to his comments on Ukraine, though, Pence and Haley are hitting back. "You have no foreign policy experience and it shows," Haley said. As Jacob said, his quick rise is drawing attacks, especially on his lack of political experience.

Haley tried to go after DeSantis as he was answering a question on Ukraine but it didn't generate the same back-and-forth as with Ramaswamy, and the moderators quickly moved on to another matter. Clearly Ramaswamy -- his lack of political experience and rapid rise in the polls -- has gotten under the skin of the other candidates on the stage and they're going out of their way to take him down a peg even if it means forgoing opportunities against the ostensible polling leader.

The discussion has turned to the U.S. relationship with China. Republicans’ opinion of China has been steadily worsening over the last six years, according to polling from YouGov/The Economist. As of their most recent survey, 91.4 percent of Republicans said China is an enemy of the United States, while just 3.7 percent said China is an ally. The last time more Republicans said that China was an ally than said it was an enemy was April 17, 2017.

Pence and Ramaswamy got into another spat, this time over Ukraine, with the vice president attacking his rival over Ramaswamy's calls to send military resources to the southern border, not Ukraine.

"Anybody that thinks that we can't solve the problems here in the United States and be the leader the free world has a pretty small view of the greatest nation on Earth," Pence said.

"I have a newsflash. The USSR does not exist anymore," Ramaswamy shot back, referring to the Soviet Union.

Nikki Haley has been in the race for longer than anyone else on the stage but hasn't had a breakout moment yet. She was clearly aiming to change that tonight, and she did have one of the most memorable back-and-forths of the night when she took Ramaswamy to task over his lack of foreign policy experience. She came out swinging early not just against Biden but against Republicans in Congress, and she was one of just a handful of contenders to make an electability argument against Trump by pointing out his low favorability ratings. But for a candidate who is polling at 3.4 percent nationwide, it's not obvious that was enough.

Burgum's presence was a victory in and of itself for the governor, given his injury today. But he got scant talking time, and his most interesting answer, when he came out definitively against a national abortion ban, isn't likely to earn him many new fans in the GOP.

But here's what I really think. The next debate is not for another month, but tomorrow, Donald Trump will surrender to the authorities in Atlanta. His mugshot will ricochet across the internet and land on the front page of every major newspaper in the country. At that point, will people be talking about tonight's debate? Or will they be back to talking about Trump? I'd put my money on the latter, and that's not good news for anyone on stage tonight.
