I vaguely remember 1980 (I was quite young then, but I followed this stuff). I recall it being SO close one week ahead of the election.
Election day was a shock - to everyone. State after state after state began to fall into the Reagan column. After the polls closed on the East Coast, the election was over.
I will be mildly shocked this time if Obama wins. If he wins it will be very close. I will not be shocked at all to see Romney win in a landslide. That's just how much this feels like 1980.
