The DeSart & Holbrook model is included in the econometric models component of the combined PollyVote. The model currently forecasts a two-party vote share of 42.3% for Clinton, and 57.8% for Trump in Tennessee. In comparison, on October 12, Clinton was predicted to end up with only 36.7% of the vote.
Putting the results in context
As any other method, models are subject to bias. In general, you should not focus too much on the results of an individual econometric model. Rather, one should examine how a model's results compare to benchmark forecasts.
