I've been following Nate Silver's numbers on the 2012 US presidential election. Simply fascinating. If he's right, and I'm led to believe his predictions are scary-accurate, this is not a race at all despite how badly the news wants to portray it as one.
They have all the predictions posted on FiveThirtyEight.
Not being American but still wanting to play along, I compiled his state by state predictions into a spreadsheet I'll be using later tonight. I'm actually much more interested in how close Silver's estimates will be to results than I am in the actual election at this point. You can download my spreadsheet below if you want to play at home, too.
Just enter the results in the Obama and Romney "Actual" columns as they roll in and you'll be able to see the difference between results and Silver's numbers.
Results
With 90%+ of results in now, I am both amazed, yet not surprised, at the results of Nate Silver's predictions. I've learned previously to take poker players proficient in statistic's predictions seriously, especially when they come out with a 91% confidence rate.
Florida still hasn't been given to Obama, but assuming he retains his slight, predicted lead there, Nate will have picked every single state correctly.
I changed my spreadsheet a bit to give me a Vote Share Accuracy (100% - absolute value of the % difference) column instead of just the % Difference from predicted. Not only did Nate pick every state correctly, his Accuracy with respect to vote share by state averages out to 96.8% with the biggest outlier being West Virginia where Obama received 14% less support than expected. He had 17 states where his predictions were 99%+ accurate.
