The DeSart & Holbrook model published an updated prediction of the election outcome. According to the model, Clinton will garner 42.6% of the two-party vote share in South Dakota, while Trump will end up with 57.4%.
Putting the results in context
In general, however, one should not have too much faith in the results of single models, because they sometimes incorporate large errors. At least, one should examine how a model's results compare to benchmark forecasts.
The DeSart & Holbrook model in comparison with PollyVote's forecast
The most recent PollyVote forecasts Trump to gain 59.4% of the two-party vote in South Dakota. The results of the DeSart & Holbrook model for Trump are thus 2.0 percentage points below the combined PollyVote in South Dakota.
