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.

This debate might be going out to a national audience, but the 2024 Republican presidential primary will be decided on a state-by-state basis — and because they’re the first to vote, Iowa, New Hampshire, South Carolina and Nevada will have an outsized impact on the race.

We’ve been collecting data on how many times each candidate has visited each early state, and there are some revealing trends. For one thing, the candidates seem to think Iowa and New Hampshire are much more important than South Carolina and Nevada. They’ve visited the first two more than 90 times each but South Carolina only 30 times and Nevada only four times. In addition, some candidates seem to be putting all their eggs in either New Hampshire’s or Iowa’s basket. For example, Christie and Hurd are focusing almost exclusively on New Hampshire — perhaps the famously independent Granite State will prove more receptive to their anti-Trump brand. Hutchinson, meanwhile, is focusing on Iowa.

Overall, Ramaswamy and Haley have paid the most visits to early states — though that’s partly because they announced their campaigns earlier than most other candidates.
