The DeSart model released an updated prediction of the election outcome. It currently forecasts a major vote share of 91.9% for Clinton, and 8.1% for Trump in Washington, D.C..
Putting the results in context
As any other method, models are subject to bias. Hence, don't have too much confidence in the results of a single econometric model. At least, one should check how a model's results compare to benchmark forecasts.
Comparison to the combined PollyVote
The current PollyVote predicts Clinton to gain 90.7% of the two-party vote in Washington, D.C.. PollyVote currently predicts Clinton to gain 1.2 percentage points less compared to the results of the DeSart model.
