Academic tenure is one of the most important foundations of a research university. Effectively getting rid of tenure would be a death sentence for the University of Florida. No serious academic would want to work there if they had options anywhere else. If anything, dragging them in front of a board every 5 years will only increase "ideological orthodoxy" or whatever he wants to call it.
Yeah but the loss of prestige of UF and FSU won't happen overnight, so it's a problem for (and that can be blamed on) DeSantis's successors.
Scott Walker did the same thing :

Yes, and this certainly led folks to leave UW-Madison for less hostile climes and has done lasting damage to its prestige and consequently its research productivity.
As a Wisconsin alumn, this is all correct. A number of professors I had back in undergrad, most of the very good, left to go to states with better working conditions for professors.
