The Jerome model is part of the econometric models component of the combined PollyVote. According to the model, Clinton will obtain 45.3% of the two-party vote share in Montana, whereas Trump will win 54.7%.
Putting the results in context
In general, however, a good strategy is to not have too much faith in the results of single models, since they often contain large errors. Rather than trusting the results from single models, the best practice is to rely on combined models or, even better, the combined PollyVote forecast that relies on different methods and data.
The Jerome model compared with PollyVote's forecast
The current PollyVote forecasts Trump to gain 56.4% of the two-party vote in Montana. The results of the Jerome model for Trump are thus 1.7 percentage points below the combined PollyVote in Montana.
