President Barack Obama's odds of winning the election have reached new highs in Nate Silver's polling forecast.

Silver's Election Day forecast gives Obama an 81.9 percent chance of winning. The previous high came after the Democratic National Convention on Sept. 12, when Silver gave Obama an 80.8 percent chance of winning. In the past week, that number has jumped 6.7 percent.
