Coastal counties on the densely populated Florida penisula are reporting higher early vote than rural counties. Pennisula counties are a mix of reliably Democratic and Republican lean, and a mixed pattern pertains.
One optimistic explanation is higher turnout rates observed in the mixed counties is reflective of new, energetic Democratic votes that will dilute the Republican lean these saw in 2016. Very small trends away from a Republican net margin in the mixed counties would effectively return the state to Democratic majority.
As in Texas, a catastrophic strategy mistake of the Trumpistas was to agitate against early voting, it effectively suppressed Republican (early) turnout in their strongest territory. (And this also reflects the generally dispirited morale of the Trumpista apologists, worn down by the chaos.)
