Maybe, maybe not. DeSantis took 60% of the vote for Governor in 2022, but his approval has tanked since then and is now underwater. Democrats also flipped Florida House District 35 in a special election, which is rated an R+15 district (it votes 15 points more towards Republicans than the national average).
Combine that with empty coffers at the Republican party, and Trump taking over the party apparatus so it can fund his legal bills at the expense of all other races and even his own campaign. They're severely off balance, and Democrats can pull a Jiu Jitsu move here by trying just a little in every single contest that's even a bit contestable. Republicans won't have a fundraising answer to that. Doesn't mean Democrats will win every seat, but it could be quite the flood.
