Newsflash: Dems are weak as heck on the local level in Florida. We won't be winning the governorship in 2018. We have come close several times, but no cigar, and this time won't be different. The dems have very weak potentials while the republicans have very strong potentials. The state is battleground in presidential elections, and lean D with Bill Nelson's seat, but besides that, Florida is a ruby red state on all other levels.
Gwen Graham is absolutely capable of winning the Governor's seat in 2018.
Granted, the FL Dem party's clownish and inept reputation is a valid concern.
