The following are final estimates, based on taking polling data over longer intervals than our usual 1-week rule. Instead, I found the period over which a state’s polling variance was minimized, as a means of identifying stability.
Sam Wang:
ELECTORAL PREDICTION (mode): Barack Obama 303 EV, Mitt Romney 235 EV. The mode is the single most frequent value on the EV histogram. It corresponds to the map below, and has a 22% chance of being exactly correct. The next-most-likely outcome is Obama 332, Romney 206 EV.
ELECTORAL PREDICTION (median): Obama 305 EV, Romney 233 EV, Popular Vote Meta-Margin Obama +2.76%. This median is almost guaranteed to be off, since 305 EV is not a common combination. It is the midpoint of all possibilities, and reflects the overall shape of the distribution. The nominal 1-sigma band is Obama [293, 332] EV.
TWO-CANDIDATE POPULAR VOTE SHARE: Obama 51.1%, Romney 48.9%.
