Someone needs to do some homework either on election rules or time zones.
The information on poll closings came from http://www.270towin.com. They have a page and set the times of state polls closing to the EST in which the last polls in that state close (if it happens to cross two time zones, like FL) which is the earliest it could be called.
They listed all closings in EST to make it simpler, so that’s the model I used.
