I think the Senate is more of a stepping stone for Scott to reach the presidency. I feel his plans were originally to challenge Hillary in 2020. If the seat is open in 2024, I think DeSantis goes after it. I think he will go after the Preaidency in 2028 if the Democrat wins.
Big question is who's likely to become the first POTUS from FL ?
A.) DeSantis
B.) Scott
DeSantis, and it's not even close. DeSantis is much younger, already more popular and doesn't look like Voldemort. I think there's a good chance that Dems will either defeat Scott or take his open seat assuming he runs in 2024.
