Rolling October Forecast Update
In addition to our September forecast model, we also have an extension of the model that provides a day-by-day updated forecast through the month of October and right up until Election Day. We will provide those daily updates here.The October Forecast Model is essentially the same as our September model in that it uses the same variables as our September forecast model, except that it uses October polling data instead of September data. Furthermore, the October model gives greater weight to the poll variable, and less weight to the prior vote variable.
November 7: Our final forecast of the 2016 presidential election projects that Hillary Clinton will defeat Donald Trump, receiving 52.83% of the national two-party popular vote to Donald Trump's 47.17%. The model's Electoral College projection suggests that Clinton will win 347 electoral votes to Trump's 191. Overall, the model gives Secretary Clinton a 98.6% probability of winning at least the 270 Electoral College votes necessary to win the election.
Below are the probability distributions for both the popular vote and Electoral College vote outcomes projected by our model in 100,000 election simulations.
In each instance, scenarios in which Secretary Clinton wins the popular vote and Electoral College all fall within the 95% confidence interval.
