His right wing polarizing blah, blah, blah is only offensive to put people who are just going to vote against him any ways and live in that bubble. More independent minded people have shown a tendency to vote for him as evidenced by the last election in Florida, with blue counties being flipped red. The media will try to make a circus show out of him anyways , and hopefully he will not be a fool and take the bait every damn time like Trump who couldn't help himself.
With all things remaining constant, and if Desantis can run a well disciplined campaign he will defeat Biden, who is FAR from a popular incumbent. There is a lot of time though, and things won't remain constant, so we will see.
