Nathaniel, I'd imagine Vivek's actual words spoken puts him even further ahead of the other contenders on stage. He even acknowledged he was "in a hurry" earlier in the debate, perhaps trying to inject a little humility and self-awareness into his image, especially after his unfavorability rating shot up after the first debate.

Ramaswamy differed with some of his opponents on the issue of Ukraine, arguing the United States should limit its support for the country in its fight against Russia.

“The reality is just because ... Putin's an evil dictator does not mean that Ukraine is good. This is a country that has banned 11 opposition parties,” Ramaswamy said.

That’s accurate. But it needs context.

Ukraine banned 11 pro-Russian parties — the largest of which occupied 44 out of 450 seats in parliament, according to Radio Free Europe. The leader of the party, Viktor Medvedchuk, is aligned with Putin. Putin is the godfather of Medvedchuk's daughter, Radio Free Europe reported.

Burgum gets a question for the first time in a while — on farmers — and turns it into a long foreign-policy answer. He’s trying to remain relevant but always seems to be late to the party on a topic that has already been talked out. According to The New York Times, he has spoken the least tonight: just five minutes and 49 seconds. By contrast, Ramaswamy has spoken the most: nine minutes, 25 seconds.

Several of the Republicans on stage touted their prioritization of border security should they win the presidency.

“What I’ll do on day one is sign an executive order to send the National Guard to partner with Customs and Border Patrol to make sure that we stop the flow of fentanyl over the border,” Christie said first. He expanded his answer to include his plans to fill the “6 million vacant jobs” in the country with legal immigrants.

“This border is going to be a day one issue for me as president,” DeSantis said, also noting that he’d administer the remain in Mexico policy, which requires migrants seeking asylum to remain in Mexico until their US immigration court date.

“We're going to declare a national emergency. Yes, we'll build the wall. We’ll do remain in Mexico,” DeSantis said.

Pence spoke about his role in negotiating the remain in Mexico policy of the Trump administration.

“I negotiated the remain in Mexico policy with the Mexican government. We used economic power to bring the Mexican government to the table. We build hundreds of miles of border wall and despite what's said here today, we reduced illegal immigration and asylum abuse by 90%. And as President of the United States, I can do it again,” he said. “I'm going to be ready on day one to get Congress to step up, secure the southern border of the United States.”

Haley cosigned on the Remain in Mexico Policy.

“Let's go back to Remain in Mexico policy,” she said. “Instead of catch and release. Let's go to catch and deport.”
Ramaswamy said that he was supportive of most of his opponents’ border positions, but that he’d go a step further: he’d end birthright citizenship for the kids of illegal immigrants.

“The Republicans on the stage are on the right side of this issue, militarize the southern border, stop funding sanctuary cities and end foreign aid to Mexico and Central America to end the incentives to come across,” Ramaswamy said.
