DeSantis wouldn’t directly answer when the moderators asked him if he would sign a national abortion ban, and Pence pounced. He comes from the social conservative wing of the party, and supports a national ban. This isn’t the first time Pence has criticized DeSantis for not being conservative enough on abortion, either.

Haley reiterated her calls for "compassion" when the country debates abortion, though she declined to state whether she would support a federal ban on the procedure.

Haley noted the uphill climb to a federal ban, referencing the 60-vote filibuster in the Senate, but said she would oppose late-term abortions and punishments for women who receive abortions.

"Can't we all agree that we should ban late term abortions? Can't we all agree that we should encourage adoptions? Can't we all agree that doctors and nurses who don't believe in abortion shouldn't have to perform them? Can't we all agree that contraception should be available? And can't we all agree that we are not going to put a woman in jail or give her the death penalty if she gets an abortion? Let's treat this like the like the respectful issue that it is," she said.

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.

Before tonight’s debate kicks off, FiveThirtyEight, The Washington Post and Ipsos partnered to ask Republican voters about how they might vote in the upcoming Republican presidential primaries. Specifically, we asked 4,968 likely Republican voters which issues are most important to them when deciding which candidate to vote for in the primaries, using Ipsos’s KnowledgePanel.

We offered respondents a list of 16 issues and allowed them to select up to three. Of the topics that we asked about, voters were most concerned about “getting inflation or increasing costs under control” (53 percent of respondents selected this issue), something Republican voters have been concerned about since at least the 2022 midterms, according to a previous FiveThirtyEight/Ipsos poll. Other issues that were top of mind for voters were “controlling immigration” (36 percent), “someone fighting against liberalism and the woke agenda” (25 percent) and “ability to beat Joe Biden” (25 percent).

If tonight’s debate touches upon those top issues, voters might get some clarity on who they are considering voting for when primary season comes around.
