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.

Haley and Ramaswamy trade insults and poll positions

Haley going after Ramaswamy was a recurring theme in the first debate. They were the standout candidates in our polling last time and there was a lot of speculation about Ramaswamy moving up in the polls — perhaps even surpassing DeSantis. But since August, Ramaswamy has actually lost support, to the point where Haley passed him in our polling average today. It makes sense that they're trading blows again; this seems to be a successful strategy for Haley, and Ramaswamy can't help but take the bait.

The candidates are discussing support for Ukraine. About half (49 percent) of Republicans and Republican-leaning independents say that vital U.S. interests are not really at stake in the war in Ukraine, according to an August Echelon Insights survey. Thirty-seven percent disagree, saying that if Russia wins, vital U.S. interests and values are threatened. Fourteen percent are unsure.

Ramaswamy’s dance card fills up

For those keeping score at hope, Christie, Pence, Scott and now Haley have all gotten into shouting matches with Ramaswamy at these debates.

DeSantis finally gets a little momentum. His "they don't care" repetition is the most impassioned he's been all night (or in either debate). But whatever applause he might have got was cut short the conversation moving on a discussion about NATO and another Scott/Ramaswamy spat.

Haley trumpets more transparent health care system. But do Republicans care that much about Obamacare anymore?

Asked about the challenges of high health care costs for Americans, Haley argued that the system needs a major overhaul, from the insurance companies to hospitals, with improved transparency for patients so they have more options and better knowledge of the costs they'll face. Still, this issue isn't as high on Republicans' list of key issues. In a recent Economist/YouGov survey, 58 percent of Republicans said "heath care" was a very important issue. That sounds high, but 81 percent said the same of jobs and the economy, 81 percent of national security and 77 percent of immigration. It's not the 2010 tea party era anymore, or even 2017, when the GOP failed to get rid of Obamacare while in full control of the government.
