Florida Gov. Ron DeSantis, who’s running hard for the 2024 Republican presidential nomination, signed a bill this week that is a masterpiece of performative McCarthyism. Ana Ceballos of the Tampa Bay Times reports that the legislation will require the state’s public colleges and universities to conduct an intrusive survey into the beliefs of students, faculty and staff.

The survey, Ceballos writes, will be used to determine “the extent to which competing ideas and perspectives are presented” and whether “intellectual diversity” is supported on campus. The new law could be the basis for budget cuts “if universities and colleges are found to be ‘indoctrinating’ students,” according to Ceballos.

Josh Kovensky of Talking Points Memo reports that, at a news conference following the signing, DeSantis castigated many colleges and universities as “intellectually repressive environments. You have orthodoxies that are promoted and other viewpoints are shunned or even suppressed.”

DeSantis’ action, needless to say, is a grotesque violation of the First Amendment. But that’s nothing new for him, as I’ve written previously.

DeSantis has also banned public school curriculum based on The New York Times’ 1619 Project, which he falsely calls “false history,” as well as instruction in critical race theory — an academic concept that, as Kovensky notes, has little to do with the diversity training and teaching about systemic racism that school systems actually engage in.

In a straw poll of potential 2024 candidates held last weekend at the Western Conservative Summit in Denver, DeSantis narrowly beat Donald Trump, according to The Hill. But first he has to win re-election as governor.

Florida had been trending bluish in recent years but appears to be moving back into the Republican column based on the past several elections. Still, a number of Democrats are lining up to challenge DeSantis, including Democratic congressman Charlie Crist, a former Republican governor himself.

The problem with McCarthy-style populism is that it’s popular — until it isn’t. We’ll see how DeSantis’ latest attack on freedom of expression plays with Florida voters.
