For those keeping score at hope, Christie, Pence, Scott and now Haley have all gotten into shouting matches with Ramaswamy at these debates.

DeSantis finally gets a little momentum. His "they don't care" repetition is the most impassioned he's been all night (or in either debate). But whatever applause he might have got was cut short the conversation moving on a discussion about NATO and another Scott/Ramaswamy spat.

Haley abruptly jumped in to hit Ramaswamy for his use of TikTok to appeal to voters, calling TikTok "one of the most dangerous social media apps," and saying she feels "dumber" every time she hears Ramaswamy talk. This moment, along with some others, revealed two things: First, Haley is on the more assertive side of the GOP foreign policy debate when it comes to dealing with China (a Chinese company owns TikTok), although Ramaswamy has said that he'd like to keep people under 16 from accessing social media. Second, she and the other Republicans on stage really don't like Ramaswamy. There've been a few other jabs at Ramaswamy tonight, but her line about feeling dumber was pretty telling.

PolitiFact has a feature we call the Flip-O-Meter. It measures — you guessed it — flip flops.

Ramaswamy entered the flip zone when he criticized TikTok and then created an account on the platform.

"I am very open to banning TikTok outright," he wrote on X in February. "In the meantime, we sit on our hands and do nothing as kids get addicted to it like it’s digital fentanyl."

Later, on Sept. 13, Ramaswamy announced that he was joining TikTok. "Yes, kids under age 16 shouldn’t be using it, but the fact is that many young voters are & we’re not going to change this country without winning," he wrote on X. "We can’t just talk about the importance of the GOP ‘reaching young voters’ while hiding in our own echo chambers."

Ramaswamy is not the first candidate to criticize a social media platform while simultaneously using it. Massachusetts Sen. Elizabeth Warren advertised on Facebook while also saying that big tech had too much power.

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.
