Didn't expect such a pro-robot stance from Christie after he attacked Ramaswamy for sounding like ChatGPT last debate.

Christie suggested that the government should refrain from regulating AI. Polling shows Republicans agree: when it comes to who should be responsible for providing solutions to AI-related issues, Republicans are more likely than Democrats to turn to companies and brands than to the government. In a July survey from Ipsos, Republicans preferred companies and brands over the government to be most responsible for creating or retaining local jobs by 29 percentage points, ensuring that AI doesn’t discriminate by 8 percentage points and ensuring AI provides accurate results by 14 percentage points. On protecting creators from unfair use of their work and preventing the spread of misinformation by AI, equal numbers of Republicans said that the government and companies should be most responsible.

Christie made an awkward joke about Biden sleeping with teacher’s unions (because he’s married to a teacher), and Pence decided it would be a good idea to remind everyone that he also is sleeping with a teacher (his wife). So, that just happened.

Pence has suggested a federal ban on gender transition-related healthcare for children. In a poll conducted by Marist College for NPR and PBS NewsHour in June, 52 percent of Republicans said only adults who are 18 and older should be able to receive gender transition-related healthcare. Nine percent said adults and children with the consent of their parents should be able to receive such care, and 37 percent said nobody, regardless of age, should be able to receive gender transition-related healthcare.

Foreign policy isn’t quite dominating this debate, but U.S. policy towards China is a prominent theme, and Ramaswamy is bearing down a lot of attacks on that.

Ramaswamy and Haley had a heated moment on the debate stage over the issue of support for Ukraine – which Haley tied to China. When Ramaswamy argued against support for Ukraine, Haley jumped in, saying that a win for Russia is a win for China, and then accused Ramaswamy of liking China.

There was also the memorable TikTok exchange between the two. Haley sniped at Ramaswamy that "every time I hear you, I feel a little bit dumber for what you say” and that he can't be trusted as he justified his choice to join TikTok after being convinced by influencer and boxer Jake Paul to join despite previously calling it "digital fentanyl." TikTok was created by Chinese company ByteDance and lawmakers have scrutinized the app over security concerns. (Ads for TikTok are also airing on Fox Business Network during commercial breaks.)

Scott also accused Ramaswamy of being ‘bought’ by China. He was likely referencing Ramaswamy's company, Roivant Sciences, announcing 5-years ago that it was partnering with China state-owned investment company CITIC Group Corp

And Pence had a similar, pointed attack: “I'm glad Vivek pulled out of his business deal in 2018 in China -- that must have been about the time you decided to start voting in presidential elections."

It’s worth noting that Haley criticized Trump too on this front, in that case for not pursuing China aggressively enough on a host of issues: “This is where President Trump went wrong.”
