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.

This was a weird debate, full of interruptions and crosstalk. I'm skeptical anyone actually "broke through" in some huge, game-changing way, and neither of the candidates I closely monitored — Haley or Christie — looked likely to suddenly gain 10 points in the polls next week.

But I did think Haley mostly had a strong night, building on her well-received showing in the first debate. She made the case for a more restrictive approach to border security, dinged Biden for his handling of the economy and immigration, and argued that TikTok is a huge danger to the country. That said, I do wonder if she might've rubbed some viewers the wrong way by saying she felt dumber after listening to Ramaswamy, and with her interruption-filled argument with Scott late in the debate. I say that because of how women are sometimes perceived in those sorts of situations — female candidates in the past have been tagged with misogynistic descriptors like "shrill," for instance. I look forward to seeing the post-debate 538/Washington Post/Ipsos poll to get a better read on how she came across.

As for Christie, he continued to be the one person in the room unafraid of attacking Trump, doing it on a good share of his answers. On the one hand, he's got nothing to lose as the GOP candidate with the worst favorability rating among Republican voters. On the other hand, his dings did occasionally free up opportunities for other candidates to make small digs at Trump without going after the former president as aggressively as Christie did. (For instance, DeSantis took a shot at Trump for adding significantly to the national debt after Christie brought it up.) Christie probably knows that he's got no chance of winning the GOP nomination, but he may also be thinking strategically about how he can help his party avoid renominating Trump. Still, it's going to take some pretty drastic changes in the race for that outcome — Trump winning the GOP primary — to not come to pass.
