DeSantis is asked about the Florida education guidelines on teaching slavery. He immediately calls it a hoax and attacks Vice President Kamala Harris (America's first Black vice president), which has been his campaign's strategy on this issue since it first broke. The moderators are quick to tee up a discussion between DeSantis and Scott, though, since the South Carolina senator was among the most outspoken Republicans against the DeSantis plan.

Moderators questioned Haley on "school choice." Seven Republican states, including Florida, passed "universal school choice" this year, which mostly means vouchers for private schools that are available to nearly all students, without income limits. Public school supporters have said these vouchers are a backdoor way of defunding public schools. In most states, states take the per-pupil allocation of tax dollars and give the money directly to parents instead, allowing them to pay for private, religious, or homeschooling courses. In many states the vouchers could go to parents who could otherwise pay for private school, and aren't enough to pay for full tuition for parents who couldn't afford it. The public is divided on these policies, but trust in public schools and public education has been declining, especially among Republicans.

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.

In polling for EdChoice conducted by Morning Consult in August, 46 percent of Republicans strongly or somewhat support school vouchers, while 11 percent strongly or somewhat oppose vouchers, 27 percent say they have never heard of them, and 16 percent don’t know. After being provided a definition, support for vouchers among Republicans increased to 70 percent, and opposition increased to 19 percent.

Hello readers! I’m Jacob Rubashkin (not 1992 VP candidate James Stockdale), and I’m a reporter and analyst for Inside Elections, a small, nonpartisan newsletter that does in-depth coverage of House, Senate, gubernatorial and presidential races. You may have seen our “race ratings,” which we publish regularly to assess each party’s chance of winning every election around the country.

Tonight, I’ll be reporting for duty as a 538 contributor, as I’ve done for many debates, primaries, and general elections over the past two years. I’ll be providing live analysis on the events playing out on stage, and also thinking about how the course of the GOP presidential primary will affect the fight for Congress next year, when Republicans aim to win back full control of Washington, D.C. (The debate is taking place in California’s 26th District, which is Solid Democratic, but right next door is the highly competitive 27th District, where vulnerable GOP Rep. Mike Garcia might not appreciate having to run with Trump at the top of the ticket).
