The DeSart & Holbrook model is included in the econometric models component of the combined PollyVote forecast. The model currently predicts a two-party vote share of 40.0% for Clinton, and 60.0% for Trump in Arkansas.
Putting the results in context
As any other method, models are subject to bias. As a result, a good strategy is to not rely too much on the results of a single econometric model. Rather than trusting the results from single models, research in forecasting recommends to look at combined models or, even better, the combined PollyVote forecast that includes different methods and data.
The DeSart & Holbrook model in comparison with PollyVote's forecast
The most recent PollyVote foresees Trump to gain 57.9% of the two-party vote in Arkansas. The results of the DeSart & Holbrook model for Trump are thus 2.1 percentage points above the combined PollyVote in Arkansas.
