The DeSart & Holbrook model is part of the econometric models component of the PollyVote forecast. The model currently forecasts a two-party vote share of 55.0% for Clinton, and 45.0% for Trump in Virginia. In comparison, on October 19 Trump was still predicted to gain 45.1% of the vote.
Historically, Virginia has been a battleground state, in which neither the Republican Party nor the Democratic Party has had overwhelming support to clinch that state's electoral college votes. This is why predictions in this state are of particular interest.
Putting the results in context
As any other method, models are subject to bias. Thus, as a general rule, don't put too much trust in the results of an individual econometric model. Instead of relying on results from single models, the recommended strategy consult combined models or, even better, a combined forecast that includes different methods and data.
