Just watch the national media start hinting/calling this at 5:00PM EST 3 hours before the polls close in the pan handle.
I know the major population is in the east but there is that whole "free & fair" elections thingy.
Florida counties that are west of the Apalachicola River are on central time, and polls in this area close at 8:00 PM EST/7:00 PM CST. This area includes three metropolitan areas:
Panama City (metro area population: 160,000)
Fort Walton Beach-Crestview-Destin (metro area population: 200,000+)
Pensacola (metro area population: 450,000)
These are not huge cities like those in central and south S. Florida, but if the statewide vote is close, there are enough people here to change the outcome - especially in this primary, since the Panhandle is solidly conservative.
