Well polled

fivethirtyeight.com has done an excellent job over the last several months of election season. Basically, they've been accumulating every poll that's conducted and aggregating them into one poll of polls.

How accurate were they? Well the last map they generated before the election was only wrong on Indiana (which had the third-smallest margin after MO and NC), with Missouri and North Carolina still too close to call at this point, but leaning the way predicted. They predicted the national popular vote to go Obama by 6.1%. Actual result (thusfar)? 63,244,187 Obama, 55,896,601 John McCain. Margin: 6.167%.

Good job, guys!
