Let's see what I remember:
Clinton: I think I found out the next day, though I barely remember
Bush: Dang, that took weeks, didn't it?! How many times did they recount Florida (or was it Ohio that year?)
Bush again: I don't quite remember that one quite as well, I was a quasi-moody teen with "bigger" issues, but I do remember being happy he won again, and surprised as the media would not shut up with negative opinions about him.
Obama: the night wasn't even close to out
Obama again: same
Trump: I remember waking up in the middle of the night and pinching myself to make sure I wasn't dreaming. Actually thought Killery would win.
Biden: Pole vault overnight.
