The Jerome model is captured in the econometric models component of the PollyVote. According to the model, Clinton will obtain 46.0% of the two-party vote share in West Virginia, while Trump will win 54.0%. In comparison, on August 16, Clinton was predicted to achieve 54.0% of the vote.
Putting the results in context
In general, however, one should not have too much faith in the results of single models, since they sometimes incorporate large errors. Instead of relying on results from single models, the recommended strategy rely on combined models or, even better, a combined forecast that incorporates different methods and data.
Results compared to the combined PollyVote forecast
The most recent PollyVote expects Trump to gain 62.5% of the two-party vote in West Virginia. The results of the Jerome model for Trump are thus 8.5 percentage points below the combined PollyVote in West Virginia.
