That’s Mostly False.

In checking previous instances when DeSantis made this same claim, PolitiFact found no evidence that critical race theory, a broad set of ideas about racism being woven into American systems, was being taught in Florida’s K-12 schools in the first place. Educators, school officials and several Florida public school districts told us that CRT has never been part of the state curriculum.

PolitiFact found a few examples of state education officials objecting to textbooks and courses they said contained CRT teaching in recent years. They show the state’s objections to prospective teaching materials, and success in preventing content it deemed to be CRT-related. But questions remain about its rationale and broad definition of the theory and other prohibited topics.

Asked about how he would fix America's education system, DeSantis said "we need education, not indoctrination."

The governor defended keeping schools open during the COVID-19 pandemic and argued that the lockdowns were connected to students falling behind.

He also touted his response to the culture wars, saying Florida "eliminated" critical race theory and gender ideology in K-12 schools.

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.

According to a Ipsos/Reuters poll from July, 77 percent of Republicans say that transgender athletes should not be able to participate in children’s sports at the elementary/high school level. Just 18 percent say they should, and 6 percent are not sure.

Money isn’t the be-all-and-end-all of political campaigns — but it sure helps, especially during the early phases of a primary. And in the 2024 pocketbook primary, the leaders so far are Trump (who raised $17.7 million in April, May and June) and DeSantis (who raised $20.1 million). These figures are striking, but you also have to account for how much time each candidate has been in the race. For instance, DeSantis jumped in in late May, so he had much less time in which to raise that money than Trump. Here’s a chart of who raised the most in the second quarter on a prorated basis.

But there’s also important context that those topline fundraising numbers don’t tell you. For instance, Burgum’s and Ramaswamy’s totals aren’t as impressive as they look — most of their fundraising came from their own wallets rather than from grassroots donors. Burgum self-funded $10.1 million of his $11.8 million haul, and Ramaswamy self-funded $5.0 million of his $7.7 million total.

On the other end of the spectrum, Scott is in better financial shape than his $5.9 million raised would suggest. That’s because he has more than $21 million cash on hand, thanks to money he carried over from his high-rolling Senate campaigns.
