Polls are open, votes are being tabulated, misguided youth are casting ballots for 3rd-party candidates to "send a message," and I'm just doing my thing at work.
I've got NBC's hour-by-hour guide bookmarked, though. And you should bookmark The Daily Parker; I will very likely live-blog again tonight, though I have promised myself to go to bed before 11 CST (unlike in 2016).
And here's my starting point, which is basically the consensus map minus Iowa and Arizona:
I'm not worried. Look, the Roman Republic fell in 49 BCE, and it only took Italy about 1,995 years to return to democracy. So why fret?
(Oh, dear. Re-reading my 2016 live blog, I see I ended with this: "Millions of people who voted for Donald Trump tonight will expect their lives to improve, with America returning to the imagined past of 'Leave It to Beaver.' What happens when they're disappointed? Which Visigoths do they invite to sack Washington?" Well, now we know.)
