I would normally be telling you to plan on turning in early. However, I've been through this before with Reagan - Carter election night.
I can still remember Walter "Crankcase" covering the returns. Even after it was obvious Reagan had won big he kept up with "At this point folks it's still too early to call. Only **% of the vote has been counted. Blah, blah, blah.... "
The media will be much worse this time around. They will drag out calling it for Trump for as long as they can. But their faces never lie. Watch their faces when they report the results. Despite all the optimistic posturing, Cronkite's face looked like he just found a turd in his punch bowl or that his wife ran off with the mailman in his prized big fancy sailboat.
The only reason I would stay up past midnight is to watch the online/on air suicides on MSNBC, CNBC, CNN, etc.
