The DeSart & Holbrook model is captured in the econometric models component of the combined PollyVote. According to the model, Clinton will garner 34.2% of the two-party vote share in Oklahoma, while Trump will win 65.8%.
Putting the results in context
As any other method, models are subject to bias. Hence, don't focus too much on the results of an individual econometric model. Instead of trusting the results from single models, the evidence-based approach is to use combined models or, even better, the combined PollyVote forecast that draws upon forecasts from different methods, each of which draws upon different data.
Results compared to the combined PollyVote forecast
The latest PollyVote anticipates Trump to gain 64.1% of the two-party vote in Oklahoma. PollyVote currently predicts Trump to gain 1.7 percentage points less compared to the results of the DeSart & Holbrook model.
