The candidates are now debating abortion, which has obviously been a hot-button issue lately, but it’s actually not super important to Republican primary voters right now. According to our FiveThirtyEight/Washington Post/Ipsos poll, only 6 percent of Republicans identified limiting abortion as one of their top three issues.

In the commercial break we get an ad targeting pro-Ukraine Republicans from Defending Democracy Together, a PAC led by a group of anti-Trump conservatives who have been very active in politics since 2017. In a poll from the Pew Research Center in June 44 percent of Republicans said the US was giving too much aid to Ukraine. I'm not sure how much this ad is going to register; Ukraine and national defense barely register in polls of Americans' most important problem these days. I think it says more about the divide in the party over Trump — who hasn't been mentioned in the debate at all so far.

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.

DeSantis revels in his record of snubbing public health recommendations to curb the spread of COVID-19. But he largely omits the closures of schools and businesses that happened under his watch.

Seven states did not issue stay-at-home orders to their residents, but not Florida.

On April 1, 2020, DeSantis issued an executive order directing all Florida residents to "limit their movements and personal interactions outside of their home." The order expired April 30, 2020, and Florida began a phased reopening in May.

Though he carved out an exception for religious services and some recreational activities, DeSantis didn't exempt in-person classroom instruction. DeSantis' Department of Education issued a March 13 recommendation that Florida schools close their facilities for an extended spring break before lengthening the closure through the end of the school year in early June.

Schools reopened in person in August 2020.
