The Jerome model released an updated prediction of the election result. It currently forecasts a two-party vote share of 86.4% for Clinton, and 13.6% for Trump in Washington, D.C.. In comparison, on August 16, Clinton was predicted to collect only 13.6% of the vote.
Putting the results in context
As any other method, models are subject to bias. As a result, one should not have too much faith in the results of a single econometric model. Instead of relying on results from single models, you should rely on combined models or, even better, the combined PollyVote forecast that relies on different methods and data.
