The DeSart & Holbrook model is part of the econometric models component of the combined PollyVote. According to the model, Clinton will collect 34.3% of the two-party vote share in Idaho, whereas Trump will end up with 65.8%. In comparison, on October 25 Trump was still predicted to collect 65.9% of the vote.
Putting the results in context
As any other method, models are subject to bias. Therefore, as a general rule, a good strategy is to not be overly confident the results of a single econometric model. Instead of relying on results from single models, forecasting research recommends to look at combined models or, even better, the combined PollyVote forecast that draws upon different methods and data.
