The Crosstab model is captured in the econometric models component of the combined PollyVote. According to the model, Clinton will obtain 39.2% of the two-party vote share in Montana, whereas Trump will end up with 60.8%. In comparison, on November 5, Clinton was predicted to win 39.9% 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, as they can contain large errors. Rather than relying on results from single models, you should use combined models or, even better, a combined forecast that incorporates forecasts from different methods, each of which draws upon different data.
The Crosstab model compared with PollyVote's forecast
The most recent PollyVote anticipates Trump to gain 57.0% of the two-party vote in Montana. PollyVote currently predicts Trump to gain 3.8 percentage points less compared to the results of the Crosstab model.
