On education, Ramaswamy says he would eliminate the Department of Education and make families more central to their children's educational choice. Central to Ramaswamy's campaign is that several federal agencies should be eliminated, but the idea of parental choice in education has swept through conservative states this year. Four Republican-led states passed new universal voucher programs that would allow parents to take tax dollars and spend them on private schools, including religious schools, or homeschool their children. More states have pushed for parental bills of rights that allow students' parents to have more of a say, and object to more, curricula.

Ramaswamy and Haley traded shots on his Israel and Russia-Ukraine views, with Ramaswamy interrupting Haley and claiming she has been saying misleading things about his proposals on Israel. Ramaswamy has called for winding down aid to Israel after integrating the country more into the region.

"I wish you well on your future career on the boards of Lockheed and Raytheon,” Ramaswamy quipped, referring to the aerospace and defense companies.

Haley struck back: "You have no foreign policy experience and it shows," she said -- and was met with cheers and applause from the audience.

Trump wasted no time attacking other Republican candidates during his pre-taped interview with former Fox News host Carlson.

"I'm saying, do I sit there for an hour or two hours, whatever it's going to be and get harassed by people that shouldn't even be running for president?" Trump said.

The 46-minute interview -- released on Carlson's X account as the GOP debate got underway -- is being seen among the campaigns as an attempt to counter-program the first debate among 2024 Republican presidential candidates on Fox News.

Let me put my wannabe political scientist's hat on for a second. We heard a lot tonight about what ails America: crime, climate change, inflation, bureaucracy (some issues are more persuasive than others). And the candidates presented various visions for combating those issues — again, some more persuasive than others! But as is always the case, a lot of what we see in these debates is just theater. There are serious doubts that these contests can really accomplish most of what these candidates are trying to sell — indeed, some of the problems may come down to the structure of these primaries in general. Next time, if the candidates are trying to run for president, they should really just stick to talking about their electability.
