Below are various tips from myself or others where noted:

Beware false stories of unprecedented lines at some precincts and desolate lines at other precincts. They may well all be true but voting patterns shift every election and getting too despondent or overjoyed based on random and possibly inaccurate anecdotes will make you crazy. Both sides have quite possibly the strongest ground games in election history so anything is possible on election day. Let it play out.
Ignore the “too close to call” game. If the media doesn’t have enough precincts reporting in a Republican state they will say the race is “too close to call.” If they don’t have enough precincts reporting in a Democrat state they will say the polls just closed so it’s too early to say anything. They do this EVERY election.
I put this on my Facebook page election night 4 years ago and have left it there. It’s as true today as it was then and is a good thing to remember no matter the outcome. “A prophet is the one who, when everyone else
despairs, hopes. And when everyone else hopes, he despairs. You’ll ask me why. It’s because he has mastered the Great Secret: that the Wheel turns.”
