The Jerome model published an updated prediction of the election outcome. According to the model, Clinton will garner 52.8% of the two-party vote share in Washington, whereas Trump will end up with 47.2%. In comparison, on August 16, Clinton was predicted to collect only 47.2% of the vote.
Putting the results in context
As a general rule, however, you should not have too much faith in the results of single models, because they can contain large errors. Rather, one should examine how a model's results compare to benchmark forecasts.
Comparison to the combined PollyVote
The most recent PollyVote predicts Clinton to gain 56.8% of the two-party vote in Washington. PollyVote currently predicts Clinton to gain 4.0 percentage points more compared to the results of the Jerome model.
