What's particularly interesting though is that this is the first presidential election where things like "house lean" and poll bias have openly been discussed. None of this got much if any play four years ago (it was a frequent topic for Nate Silver but I didn't see it much beyond that) but now it's everywhere, the result being a series of polls each side trusts in exclusion of the others and a parsing of the politics of likely voter models -- one favoring the Democrats and the other the Republicans -- neither of which can be concurrently right.
I mean, it's one thing to know you're going to get beat and say the other side cheated. It's another to actually think you're going to win and have the rug totally pulled out from under you by reality. But that's what's going to happen tomorrow for a whole bunch of people. Either a serious (conservative) guy like George Will is right in saying Romney is getting like 320+ electoral votes, or a serious (liberal) guy like Joe Trippi is right in saying Obama's looking at 303 or perhaps even 332 electoral votes. One of them is going to look like an idiot come Wednesday morning. Perhaps even both.
