The DeSart & Holbrook model is part of the econometric models component of the combined PollyVote. According to the model, Clinton will garner 42.6% of the two-party vote share in South Dakota, whereas Trump will end up with 57.4%. In comparison, on October 12 Trump was still predicted to gain 62.1% of the vote.
Putting the results in context
Individual models can contain substantial errors, which is why they should be interpreted with caution. Instead of relying on results from single models, one should rely on combined models or, even better, the combined PollyVote forecast that relies on different methods and data.
Comparison to the combined PollyVote
The most recent PollyVote predicts Trump to gain 58.9% of the two-party vote in South Dakota. PollyVote currently predicts Trump to gain 1.5 percentage points more compared to the results of the DeSart & Holbrook model.
