While many candidates onstage have sparred with each other -- including Haley and Ramaswamy swapping sharp words on foreign policy -- Scott has yet to engage with any of the other candidates.

Much of his remarks have almost word for word repeated elements from his campaign stump speech. When asked about China, which he has addressed in other appearances, he pivoted to speaking about the U.S. border.

Asked to raise their hand if they would not increase aid to Ukraine, DeSantis did so, saying that "Europe needs to step up. They need to step up and do their job."

He argued: "I would have Europe pull their weight. ... Our support should be contingent on them doing it.

DeSantis -- who had received backlash from some other politicians for seemingly backtracking on support for Ukraine -- pivoted to say that he wasn’t going to send troops overseas but rather down to the Southern border.

According to a Pew Research Center survey from August 2022, 72 percent of Republicans say that increasing security on the U.S.-Mexico border is a very important goal for immigration policy. However, Hispanic and non-Hispanic Republicans differ on this issue, with 55 percent of Hispanic Republicans saying border security is a very important goal, compared with 74 percent of non-Hispanic Republicans.

Baier and MacCallum have repeatedly sought to stop Pence from interrupting their questions or other candidates' answers -- an example of a debate in which the candidates were sometimes freewheeling in how they answered questions and handled the time limit rules the moderators had set out.

While asking Hutchinson about the border, Baier again had to again stop Pence, saying, "Vice President Pence, it really doesn't help."

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.
