DeSantis quickly shut down a question from Fox News' Martha MaCallum asking candidates to raise their hands if they believe human behavior is causing climate change.

"Look, we’re not schoolchildren. Let's have the debate," DeSantis said.

He then largely declined to answer the question at hand, instead criticizing President Joe Biden's response to the Maui wildfires in Hawaii. (Biden's aides have pushed back on such criticism.)

"As somebody that has handled disasters in Florida, you have to be there present and helping people who are doing this," DeSantis said.

On the climate change question, DeSantis once again steered things toward one of the strengths of his record: handling natural disasters. Eighty percent of Republicans viewed his response to Hurricane Ian in 2022 favorably, and he got a boost in the polls after the hurricane hit, perhaps contributing to his 19-point victory in the 2022 gubernatorial race.

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.

If you’re trying to gauge which Republican primary candidate would perform best against Biden in next year’s general election — their “electability” — their favorability ratings are a helpful signal. According to FiveThirtyEight’s polling averages, Biden is viewed favorably by 41.6 percent of U.S. adults and unfavorably by 53.9 percent, for a net rating of -12.3 percentage points. That compares to a net favorability rating for Trump of -16.5 points (39.7 percent favorable and 56.2 percent unfavorable). Given those numbers, a reasonable observer might expect Biden to beat Trump in the popular vote in 2024, all else being equal. (Of course, it never is).

Many of the other candidates — like Ramaswamy and Scott — have higher net favorability than Biden. But that doesn’t mean they’d actually perform better against the incumbent president in a general election. Candidates’ net favorability tends to decline as more people know them. To get a sense of how popular some of the less-known candidates are, we can use a regression model to quantify the relationship between name recognition and net favorability and then estimate what each candidate’s net favorability rating should be based on how many people know them. Then, we can compare the actual number to that benchmark and get a better sense of who is overperforming or underperforming. On this metric, Scott and Ramaswamy score the best of the non-Trump field, with current net ratings that are 5 and 6 percentage points, respectively, higher than we would predict for them. Christie, meanwhile, trails the field with a net favorability rating 15 percentage points lower than his benchmark.
