The DeSart & Holbrook model is part of the econometric models component of the combined PollyVote forecast. It currently forecasts a major vote share of 35.7% for Clinton, and 64.3% for Trump in Oklahoma.
Putting the results in context
As a general rule, however, you should not have too much faith in the results of single models, because they may contain large errors. Rather, one should check how a model's results compare to benchmark forecasts.
Results compared to the combined PollyVote forecast
The latest PollyVote anticipates Trump to gain 64.2% of the two-party vote in Oklahoma. The results of the DeSart & Holbrook model for Trump are thus 0.1 percentage points above the combined PollyVote in Oklahoma.
