After last month’s debate, we declared Haley as a big debate winner, according to our previous poll with The Washington Post and Ipsos. When likely Republican primary voters who watched the debate were asked whether they’d consider voting for each candidate, Haley jumped from 30 percent before the debate to 47 percent after. Overall, participation in the debate was beneficial for candidates, and absence from the debate was (at least marginally) detrimental.

We’ll be following up with the same group as our pre-debate poll to see how participants performed and what respondents' views on all of the candidates are. Check back in with 538 tomorrow afternoon for our post-debate analysis.

DeSantis gets another chance to be the adult in the room by rejecting the premise of that moderator question. He did the same thing in the first debate when the moderators asked candidates to raise their hands if they believed in man-made climate change.

Moderator Dana Perino asked every candidate to write down which challenger they would “vote off the island.” DeSantis refused, prompting Perino to rework her approach, asking for his mathematical approach to winning the nomination — and of course, that’s not going to work with a politician. Christie, however, interjected that he’d be just fine voting Trump off the island.

DeSantis claimed that his 1.5 million-vote victory was the largest in a Florida gubernatorial election in state history. Now, his nearly-20 percentage point margin of victory was quite large in what has historically been a swing state. But it's quite misleading to use the raw vote margin since population has changed quite a bit over time! This is especially true in a state like Florida, which has grown by leaps and bounds. For instance, a candidate would've had a tougher time winning by 1.5 million votes in 1990, when the state had a population of about 13 million, than in 2022, when the state had a population of about 22 million.

Hours before the seven Republicans who qualified for the second RNC debate would have taken the stage at the Reagan Library in Simi Valley, California, a few hopefuls shared their pre-game time rituals.

Pence got a workout in, did some light preparation work, and spent time with his wife, former Second Lady Karen Pence, daughter Charlotte and granddaughter Etta, according to a campaign adviser.

Scott spent the day with family. He took time for prayer, some devotionals, and worked out at the gym. The tune on repeat in his headphones this week has been "Way Maker" by Leeland, according to a source familiar with the campaign.

Ramaswamy had breakfast, worked out and played with his two sons Karthik and Arjun until he worked out again later, according to spokesperson and senior advisor Tricia McLaughlin. The tech entrepreneur also toured the Reagan Library, where he told reporters that he was “feeling good” ahead of the debate.

Haley's team shared the former ambassador’s playlist that she listened to before the debate. They include:
