Things I noticed:
People are interacting with DeSantis via various forms digital media but never in a face to face setting. It seems he is trying to viewhimself as a martyr that is awakening the people.
Incredibly complex language and termonology, ruins any authentic populist perspectives and makes him sound like a texbook R from 2000.
The guy sounds boring, he doesn't excite anyone. It's really hard to come across as a fighter with his monotone voice that sounds like a documentary narrator.
It's still early and things can change, but if this is what his campaign is going to be like then Trump is likely going to cruise. I think even Haley is doing a better job than this.
