It's weird to me that DeSantis is polling as so much more popular than Rubio. I would think it would be the opposite. Who are all these pro-DeSantis/anti-Rubio people?
Rubio has had a lot of time to disappoint people. He's been in the Senate for 12 years without much in terms of accomplishment and has been exposed as hollow by his lack of firm principles and poor presidential campaign. Desantis is still new enough on the big stage to keep his flaws out of the public eye. Essentially, Desantis is still a rising star while Rubio hasn't been one for years.
