The DeSart & Holbrook model published an updated prediction of the election outcome. It currently forecasts a two-party vote share of 58.6% for Clinton, and 41.4% for Trump in Washington.
Putting the results in context
As any other method, models are subject to bias. Hence, one should not focus too much on the results of a single econometric model. Rather than relying on results from single models, the recommended strategy look at combined models or, even better, a combined forecast that draws upon different methods and data.
