He and Gov. Abbott seem to be the current standard bearers for the Trump "doctrine", such as it is. I think DeSantis has ambitions of higher office, so he'll keep catering to the Trump base. That includes egregious (and intentional) mis-management of quarantine measures, disparaging Dr. Fauci, and embracing anti-science. I think it would save a lot of lives if Trump were to vanish from the scene right now, but that doesn't seem likely.
