The second Republican debate of the 2024 presidential primary, taking place at the Ronald Reagan Presidential Library, has just come to an end.

The affair was more raucous than the first debate, which took place over a month ago. Candidates interrupted one another much more regularly and several — most notably former Vice President Mike Pence and former New Jersey Gov. Chris Christie — have directly criticized front-runner Donald Trump, who elected not to show up tonight. The two candidates from South Carolina, former U.N. ambassador Nikki Haley and Sen. Tim Scott, went after one another for their records on spending, and seemingly everyone who had the chance to take a shot at entrepreneur Vivek Ramaswamy did so.

Flip-flop on TikTok?

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.

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.

How things are going

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.
