Haley finally gets a question on foreign policy, a strong suit for the former U.N. Ambassador. She defends American support for Ukraine and ties it to the fight against China. But while the moderators teed her up to attack DeSantis, she instead pivots to Ramaswamy. She's pretty fiery in her back-and-forth with him, saying he has no foreign policy experience "and it shows."

On Russia's invasion of Ukraine, Christie referenced his recent trip to the war-torn country and said that he "wanted to see for myself what [Russian President] Vladimir Putin's army was doing to the free Ukrainian people."

"They have gouged out people's eyes, cut off their ears and shot people in the back of the head," Christie said of the brutality he saw.

"This is the Vladimir Putin who Donald Trump called 'brilliant' and a 'genius,'" he continued. "If we don't stand up against this type of autocratic killing, we will be next."

Born in 1985 and only 38, Ramaswamy may be the only candidate on stage who was too young to remember the Cold War. The USSR dissolved when he was 6.

The debate over Ukraine is a window into the intraparty battle between its previously more dominant neoconservative wing that lost credibility during and after the George W. Bush years and the comparably isolationist wing that's gained ground with Trump's time in office. Ramaswamy, as an avatar for the New Right, specifically name-checked the Iraq War, saying the Ukraine conflict could lead to American intervention. By comparison, Pence and Haley, more traditional conservatives who have foreign policy experience from their time as vice president and U.N. ambassador, respectively, were especially vocal in defending U.S. support for Ukraine.-Analysis by Geoffrey Skelley of FiveThirtyEight

Members of DeSantis’s campaign are still upset about a debate memo that was prepared and published last week by a super PAC supporting the governor, a source close to the campaign told ABC News on Wednesday, describing those members of his team as “wildly irritated.”

Chief among the complaints is that the memo, which detailed suggested approaches and lines of attack, effectively handcuffs DeSantis by preventing the governor from using any of the advice on stage lest he invite attacks from opponents for using lines manufactured for him by other people.

The memo included research documents that show that Axiom Strategies, a consulting firm tied to the super political action committee, anticipated that the biggest hits to DeSantis would include his battle with Disney -- ABC News' parent company -- past comments on Ukraine, Florida's Black history standard, the culture wars and abortion.

The packet also included past comments made by presidential hopefuls attacking DeSantis on those specific subjects.

DeSantis himself has downplayed the memo, telling Fox News recently, “It’s not mine. I haven’t read it. It’s just -- I think it’s something that we have put off to the side.”
