I'm 34 years old, so I remember 2012, 2008, 2004, 2000, and even a bit of 1996.
I remember 1996 being a pretty big blowout, and there wasn't any doubt that Clinton would win.
2000 was incredible. I was a freshman in college and taking an "Intro to Poli Sci" class. I remember Al Gore coming to my campus, snipers on the rooftops, a pretty pumped up crowd waiting for him. The Monday before the election my Poli Sci professor lectured a bit and then said "we'll talk about how the result on Wednesday." Well, Wednesday came, the professor walked to the front of the class, and said "well, there isn't a result to talk about." And then we talked about what was likely to happen over the next few weeks. But people knew it'd be a nail biter.
2004 was interesting. It was going to be another nail biter. Everyone's eyes were on OH and FL. As October rolled on, Kerry was being successfully portrayed as a know-it-all liberal elite (remember the windsurfing photo, the fact he could speak French) who abandoned his friends in Vietnam... Then there was the gay marriage amendments that were being voted on in many states which brought out the conservative base. Kerry simply let Bush guide people's perceptions of him, and then brought out the social conservatives in droves. In hindsight, it might be the last time the Reagan coalition won the presidency.
2008 was a landslide. No doubt that Obama was going to win. Although I was wondering if he'd be assassinated. Palin was a laughing stock. McCain was trying to win an election after the Republicans tanked the economy and tanked Iraq.
There were a lot of nerves. Obama's performance in the first debate cast doubt on him. Republicans were pushing hard against Obamacare. I was living in Ohio and it was pretty intense there, but over the last two days I felt good that Obama would win.
I guess this feels a bit like 2012. But it's been a roller coaster. I mean, Hillary was up 11% just 3 weeks ago, then the FBI thing. I feel confident she'll win (maybe not a 99% like Wang has it) but confident nonetheless. I feel a bit despondent that my home state of MI might actually vote fro Trump, though. This could really open up some paths for him to win, but I think Hillary's numbers could blow up a little as the FBI thing vindicates her 48 hours before election day.
