The problem for the democratic party in Florida for the next couple of cycles is that their bench has been completely wiped out, with only Fried and Stephanie Murphy constituting strong statewide candidates. Patrick Murphy has become a joke and the sheen has worn off Gillum
Fried came out of nowhere and won statewide. Dems have a fine bench in the Central Florida Mayors and their congressional delegation.
Also, I think the importance of having a "bench" is overrated in general, and especially in Beltway Media and on sites like this one: no one had ever heard of Doug Jones before 2017, and if you look at the background of most current U.S. senators, most were U.S. Reps, mayors, or state legislators before, of which the FL Dems still have plenty.
