To Nate Cohn, who previewed the vote counting and reminded us before the election (as Andrew Sprung reminds us today) that Barack Obama would gain considerable ground on Mitt Romney after election day -- a lot after election day.
The Cook Report's David Wasserman has been keeping tabs on the current vote totals, and finds today that Obama's lead is up to 3.1% nationally, and still rising. That's up from 2.3% the morning after election day; I'm not sure what it was when the networks closed up shop on election night. That's a pretty large swing! It seems pretty likely that Obama's lead will wind up a full percentage point higher than it was at that point. Of course, no one really cares that much is a national lead goes from 2.3 to 3.1 percent, but they sure might if it were to go from a 1% GOP lead on Election Day to, say, a half a point lead for the Democrat when all was said and done.
Meanwhile, Colorado was at 4.7% on the morning after and is now at 5% even (actually a 4.98% lead, just below Obama's 5.02% lead in Pennsylvania as of now).
So a five point shift to Romney, with uniform swing, would have put Romney in the Electoral College lead on the morning after the election, with a 0.3% margin in Colorado, and with a fairly massive 2.7% national vote lead. Two weeks later, Obama would have emerged as the winner by taking Colorado by the narrowest of margins, while still trailing the national vote by just under 2%. Yeah, that's gonna cause some trouble. Indeed -- Iowa, New Hampshire, Wisconsin, Nevada and Minnesota would all have been very close, and in this scenario all of them would be subject to recounts, allegations of voter fraud, challenges to provisional ballots, and the rest of it.
I'm not sure there's much to be done about any of this, but Cohn deserves the Catch for pointing it out in advance, and it's really something that everyone should be extremely aware of in advance next time around.
Of course, another reasonable reaction would be to find a way to make the mechanics of elections a lot smoother.
Anyway, all of this is at least a mess just waiting to happen.
