The DeSart & Holbrook model released an updated forecast of the election outcome. The model currently forecasts a two-party vote share of 42.1% for Clinton, and 58.0% for Trump in Montana.
Putting the results in context
As any other method, models are subject to bias. In general, one should not rely too much on the results of a single econometric model. Instead of relying on results from single models, the evidence-based approach is to rely on combined models or, even better, a combined forecast that incorporates different methods and data.
