 On the morning of the November 6, 2012 presidential election, Silver's model gave President Barack Obama a 90.9% chance of winning a majority of the electoral votes.At the end of that day, after the ballots had been counted, the 538 model had correctly predicted the winner of all 50 states and the District of Columbia.Silver, along with at least two academic-based analysts who aggregated polls from multiple pollsters, thus got not only all 50 state predictions right, but also all 9 of the "swing states".
