Republican debate highlights and analysis: Candidates squabble in Simi Valley
2024 hopefuls argued over education, spending and border security.
The second Republican debate of the 2024 presidential primary, taking place at the Ronald Reagan Presidential Library, has just come to an end.
The affair was more raucous than the first debate, which took place over a month ago. Candidates interrupted one another much more regularly and several — most notably former Vice President Mike Pence and former New Jersey Gov. Chris Christie — have directly criticized front-runner Donald Trump, who elected not to show up tonight. The two candidates from South Carolina, former U.N. ambassador Nikki Haley and Sen. Tim Scott, went after one another for their records on spending, and seemingly everyone who had the chance to take a shot at entrepreneur Vivek Ramaswamy did so.
Read below for highlights, excerpts and key moments.

Trump leads the endorsement primary
The Republican presidential candidate with the most institutional support is the one who decided not to show up tonight: Trump. He has 364 endorsement points, according to 538’s endorsement tracker, which assigns a certain number of points to each endorsement a candidate gets depending on how prominent the endorser is. DeSantis is in second place, but way, way behind, with 43 endorsement points.
This is important because the candidate with the most endorsement points by the time of the Iowa caucuses usually wins the nomination. Given how strong Trump’s polling lead is at the moment, one of the few things that could (maybe) stop him is Republican party leaders closing ranks around another candidate. So far, there’s no sign of that happening.

How well do likely Republican voters think candidates will perform?
In anticipation of tonight’s debate, we again partnered with The Washington Post and Ipsos to ask likely Republican primary voters what they think about tonight’s debate participants and the candidate field in general.
The 5,002 likely Republican primary voters we polled using Ipsos’s KnowledgePanel expect DeSantis and Ramaswamy to perform best, out of the seven-candidate field. According to a five-point scale that we calculated using respondents’ answers (with 1 being “terrible” and 5 being “excellent”), likely voters expected both DeSantis and Ramaswamy to perform “very good” (3.44 and 3.43 out of 5, respectively). They thought Haley would perform third-best (3.40 out of 5) and Scott fourth (3.20 out of 5). All of this is fairly in line with their pre-debate expectations in August.
When it comes to which candidates respondents are interested in, Haley saw the biggest bump since our poll before last month’s debate — 31 percent are now considering voting for Haley, up from 25 percent. Although she now has the third-most prospective support, she’s still got a long way to go compared to Trump (66 percent) and DeSantis (49 percent). About 1 in 4 likely Republican primary voters are also considering voting for Ramaswamy and Pence.
We’ll be watching to see how the candidates fare tonight, and if debate watchers’ opinions on who they’re considering voting for will change after tonight’s performances.

Are the presidential contenders running for president or for Trump’s VP?
Outside of the Trump-critical wing of the Republican primary — featuring Christie and Hutchinson, with major appearances by Pence — most of the presidential field has tip-toed around Trump, careful not to attract his ire. But in the last couple weeks, some candidates have started taking on Trump more directly, jeopardizing their prospects as his running mate.
Trump was already unlikely to name a challenger as his VP pick. Of the 19 unique Democratic and Republican presidential nominees since 1972, only four selected a running mate who had run against them in the same year’s primary. And Trump is even more prickly about loyalty than his recent predecessors.
Last week, we analyzed the tweets of the six highest-polling Republican candidates (other than Trump) in 538’s national polling average. Until recently, DeSantis had hardly acknowledged the former president, mentioning Trump just once since Jan. 6, 2021. But that changed last week, when DeSantis published three critical tweets about Trump. Scott, meanwhile, has largely kept his social media tone neutral toward Trump, but we did see a rare direct criticism on the stump last week, when he said Trump’s suggestion that he’d seek a compromise on federal abortion legislation was the wrong approach. Haley’s tone toward Trump shifted earlier this summer, from cautious to directly critical.
Tonight could tell us whether these recent instances of criticism are the beginnings of a new trend in which the GOP field actually tries to topple the front-runner.

DeSantis is the most popular Republican on stage tonight
Everyone obsesses over horse-race polls, but another important data point in the primary is each candidate’s net favorability rating, or the share of Republicans who view them favorably minus the share who view them unfavorably. In a horse-race poll, respondents can only choose one option, but in reality, there are probably multiple candidates they might consider voting for. Net favorability rating gives us a proxy for how many voters might be open to supporting a given candidate, even if they are not currently a voter’s first choice.
Unsurprisingly, Trump is the most popular candidate in the GOP field, with a net favorability rating of +53 percentage points among Republicans, according to the 538 average. But DeSantis isn’t too far behind him at +43 points, indicating that, although he isn’t many Republicans’ first choice, most of them still like the guy. Ramaswamy, Scott and Haley also have strongly positive net favorability ratings, suggesting that they are the five most plausible Republican nominees. By contrast, Pence and Christie are underwater with Republican voters, making it difficult to see how they can win the nomination.

Final thoughts: More of the same, with little extra grandstanding
We got glimmers of candidates attempting to narrow down the GOP primary field. Haley and Scott sparred over South Carolina politics, Pence criticized DeSantis’ spending in Florida, DeSantis criticized Trump’s stance on abortion, and just about everyone tried to take Ramaswamy down a peg (though that might have been a result of their frustration with him rather than actual political strategy). But what Republicans need in order to wage a credible challenge to Trump’s frontrunner status is to shake up the field, and I don’t know if we saw that tonight. It looked like we might get a little closer to winnowing down the field when moderator Dana Perino asked everyone to write down who they should “vote off the island” — but DeSantis, making a show of being above that sort of petty question, prevented us from getting any answers.
