Ramswamy defended his position that the U.S. should arm the Taiwanese people with assault-style weapons, despite a Taiwanese zero-gun policy, and added the U.S. should “for the foreseeable future” promise to defend the self-governing island from China, which claims it as its own.

Ramaswamy drew a contrast with DeSantis, who hewed closer to the strategic ambiguity behind America’s longstanding deterrence posture. Haley, separately, said America must continue to defend Ukraine as a signal to Beijing that it can’t attack Taiwan and said the U.S. should not depend on China for national security.

Christie said he would engage militarily if Taiwan is invaded by China.

Asked what threats she worries could blindside the U.S. amid what federal officials have called a heightened threat level during the Israel-Hamas war, Haley focused on "foreign infiltration."

"America right now is acting like it's Sept. 10. We better remember what Sept. 12 felt like, because it only takes one," she said.

"We've got to get the foreign infiltration out of our country -- whether it's in our schools, whether it's on our social media, we need to stop all foreign lobbying that's happening to members of Congress, and we need to start securing America again," she continued.

Ramaswamy again trained his ire toward Haley, with whom he has feuded across the debates this year, saying she was “woke” and “had a corruption problem.” Ramaswamy raised a notepad which had the message “NIKKI=CORRUPT.” A chorus of boos filled the venue.

The entrepreneur said Haley would “send your kids to die so she can buy a bigger house.”

Given the chance to respond, Haley said only, “No. It’s not worth my time to respond to him.”

In that question, Tom Fitton just pointed out, incredulously, that the U.S. Postal Service is more popular than the FBI. But this actually isn’t surprising -- the Postal Service is quite popular! According to a 2023 poll from the Pew Research Center, 77% of Americans have a favorable view of the Postal Service. It’s the second-most popular federal agency, after the National Park Service.

DeSantis said Haley opposed Florida’s ban on gender-affirming care, saying she thought “it’s fine and the law shouldn’t get involved with it.” She doesn’t think it’s “fine.” In a June interview on “CBS Mornings,” Haley said “the law should stay out of it” but it should be up to parents until the child is 18. In the interview, Haley said children should “make more of a permanent change” after they turn 18.

During the debate, Haley likened her position on gender-affirming care for minors to age requirements for getting a tattoo: “I said that if you have to be 18 to get a tattoo, you should have to be 18 to have anything done to change your gender.” We’ve heard that comparison before. For what it’s worth, two-third of U.S. states allow minors to get tattoos if their parents consent. And medical experts have told us gender-affirming care is in many cases considered medically necessary, while tattoos are cosmetic.
