Putting the results in context
As any other method, econometric models are subject to bias. In general, don't have too much faith in the results of a single econometric model. Instead of relying on results from single econometric models, you should use combined econometric models or, even better, the combined PollyVote forecast that relies on different methods and data.
Results vs. other econometric models
If we look at an average of Montana econometric models, Trump's current two-party vote share is at 57.3%. In comparison to his numbers in the Jerome model Trump's econometric model average is 2.6 percentage points higher.
