The Crosstab model is captured in the econometric models component of the PollyVote. It currently predicts a major 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. Therefore, as a general rule, don't have too much confidence in the results of a single econometric model. At the very least, one should examine how a model's results compare to benchmark forecasts.
