1. Electoral college does make elections predictable.
I mean it doesn't matter if Oklahoma goes 70-30 percent red or 51-49. It's still worth only 7 electoral votes. And it's quite possible that the most extreme states are the ones where additional popular votes are won, and the more evenly divided states don't move very much. I mean, in the extreme states, the social pressure to vote with the crowd is stronger.
Really, what were the states that were really in any doubt this time? Not Ohio. In my opinion, Florida, North Carolina, and Virginia. That's it. If Obama had lost the two he won, that would have put him at 290. Still a clear victory.
