The DeSart & Holbrook model is captured in the econometric models component of the combined PollyVote. According to the model, Clinton will obtain 54.3% of the two-party vote share in Pennsylvania, whereas Trump will win 45.7%. In comparison, on October 22, Clinton was predicted to gain 54.4% of the vote.
Putting the results in context
As a general rule, however, one should not have too much faith in the results of single models, because they may incorporate large errors. Rather than relying on results from single models, the best practice is to use combined models or, even better, the combined PollyVote forecast that relies on different methods and data.
