A summary of how election night 2016 played out from 7:00PM to midnight. You may want to use this as reference for election night 2020 and any other election night.

I've used the 4plebs archive at archive.4plebs.org/pol/ to dig into posts from /pol/ from election night to see the results they shared at each point in time, and I also used the NYTimes 2016 Live forecast pages to assess how margins for the race changed as the night went on.

From 7:00PM EST to 8:00PM EST Trump and Hillary exchanged leads multiple times in Florida

Let's start with this screenshot of Florida results from 7:09PM EST, as you can see they were disproportionately from Trump friendly areas.
