The DeSart & Holbrook model is captured in the econometric models component of the PollyVote forecast. According to the model, Clinton will receive 66.4% of the two-party vote share in Massachusetts, whereas Trump will win 33.7%.
Putting the results in context
As any other method, models are subject to bias. Therefore, as a general rule, one should not focus too much on the results of an individual econometric model. Instead of relying on results from single models, forecasting research recommends to rely on combined models or, even better, the combined PollyVote forecast that uses forecasts from different methods, each of which draws upon different data.
