Ramaswamy's on-stage combativeness appears to have paid off, as he’s the top trending topic on X in the U.S. at the moment.

Note: Another trending hashtag, #TellUsNicki, refers to Nicki Minaj, not Nikki Haley.

After the debate ended, Ramaswamy walked right past Haley to shake Christie’s hand — and Ramaswamy appeared to greet all of his opponents but her before walking off. Haley didn't make eye contact with him either as both spoke to their opponents and then greeted family members.

Ramaswamy was not the target he was in the first two debates. See the debate attack tracker.

Scott said he would ban abortions from occurring “up until the day of birth” and "certainly wouldn't allow" the infanticide he said a Democratic governor had talked about.

Scott's claims are misleading. The vast majority of abortions occur in the first trimester. In 2020, just 0.9 percent of abortions occurred after 21 weeks of gestation, according to the Centers for Disease Control and Prevention. Abortions after the point of viability are often due to severe congenital abnormalities or maternal complications. Ninety-three percent of abortions in 2020 occurred before 13 weeks of gestation.

Infanticide is already illegal. Then-Virginia Gov. Ralph Northam made controversial remarks about giving families choices on resuscitating dying infants. Trump made a similar false claim during his 2019 State of the Union, and NBC News debunked it then.

Ramaswamy also brought up a theory that’s been circulating through the GOP that Biden will not ultimately be the Democratic nominee. This unfounded theory has been big with Republicans lately.

Big applause at the Iowa watch party for Ramaswamy saying Biden isn’t really president, echoing conspiracy theories.

And one final glance from Haley to Christie during Ramaswamy’s closing remarks. That marks at least three from my watch in the debate hall.

Kyle Claire, 20, is a college Young Republican from the University of Iowa. Claire is a DeSantis fan who was jazzed about Iowa Gov. Kim Reynolds’ recent endorsement of the Florida governor. He’s still considering Haley though, and feels like DeSantis waffled on his stance on Ukraine on the debate stage tonight.

“I think DeSantis needs to take a little bit stronger stance on Ukraine,” said Claire, a junior studying political science. "There’s nothing more 'America First' than ensuring our security, and that includes ensuring the security of our allies, too."

From Texas: Abortions in Texas have dropped significantly since Roe vs. Wade was overturned last year. The state already had one of the strictest laws and now abortions hardly ever happen. According to this 2023 report from the Society of Family Planning, roughly 2,650 abortions were performed per month from April to June 2022 in the state. Then came Dobbs in June 2022. From then until December 2022, 10 abortions were performed per month.
