Haley tried to defuse the flying attacks, including another round of barbs between Christie and Ramaswamy.

"This is exactly why Margaret Thatcher said if you want something said, ask a man. If you want something done, ask a woman," Haley said.

"If you want something said, ask a man. If you want something done, ask a woman," says Haley (quoting former U.K. Prime Minister Margaret Thatcher), chastising both Christie and Ramaswamy while drawing attention to the fact that she's the only woman up on stage tonight.

Pence and Ramaswamy engaged in the first fiery back-and-forth of the night, with the former vice president going after the entrepreneur in an unprompted attack.

"You got people on this stage that won't even talk about issues like Social Security and Medicare," Pence said. "Vivek, you recently said, a president can't do everything. Well, I got news for you … the president of the United States has to confront every crisis facing America. I will put our nation back on the path to growth and prosperity and restore fiscal responsibility."

Ramaswamy didn't directly take Pence on in response, saying he'd tap into all of America's energy resources.

Pence didn't let Ramaswamy off the hook, firing back, "Let me explain it to you. I'll go slower this time."

Burgum finally gets a word in, and starts with an easy "break a leg" joke. Notable that he pivots pretty quickly from the economy write large to specifically talk about energy. He's come armed with the statistics you'd expect from the leader of one of the top energy-producing states in the union.

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.”
