Ramaswamy came out hitting the other candidates, saying he's the only one who hasn't been bought and sold. When it came to his comments on Ukraine, though, Pence and Haley are hitting back. "You have no foreign policy experience and it shows," Haley said. As Jacob said, his quick rise is drawing attacks, especially on his lack of political experience.

Haley tried to go after DeSantis as he was answering a question on Ukraine but it didn't generate the same back-and-forth as with Ramaswamy, and the moderators quickly moved on to another matter. Clearly Ramaswamy -- his lack of political experience and rapid rise in the polls -- has gotten under the skin of the other candidates on the stage and they're going out of their way to take him down a peg even if it means forgoing opportunities against the ostensible polling leader.

The discussion has turned to the U.S. relationship with China. Republicans’ opinion of China has been steadily worsening over the last six years, according to polling from YouGov/The Economist. As of their most recent survey, 91.4 percent of Republicans said China is an enemy of the United States, while just 3.7 percent said China is an ally. The last time more Republicans said that China was an ally than said it was an enemy was April 17, 2017.

Pence and Ramaswamy got into another spat, this time over Ukraine, with the vice president attacking his rival over Ramaswamy's calls to send military resources to the southern border, not Ukraine.

"Anybody that thinks that we can't solve the problems here in the United States and be the leader the free world has a pretty small view of the greatest nation on Earth," Pence said.

"I have a newsflash. The USSR does not exist anymore," Ramaswamy shot back, referring to the Soviet 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.”
