Republican debate highlights and analysis: Fiery faceoff on Trump, Ukraine and more

Scott just took a question about national security and turned it into one about immigration, saying our Southern border is the greatest national security threat. Ramaswamy did something similar earlier. If you look at the polling, it’s easy to see why: According to our FiveThirtyEight/Washington Post/Ipsos poll, 36 percent of Republicans identified “controlling immigration” as one of their top issues in the primary — second only to inflation and rising prices.

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.
