The Crosstab model released an updated prediction of the election result. According to the model, Clinton will obtain 40.5% of the two-party vote share in South Dakota, while Trump will end up with 59.5%. In comparison, on October 26, Clinton was predicted to end up with 41.0% of the vote.
Putting the results in context
As any other method, models are subject to bias. Hence, one should not have too much confidence in the results of a single econometric model. At least, one should check how a model's results compare to benchmark forecasts.
Results compared to the combined PollyVote prediction
The current PollyVote expects Trump to gain 58.2% of the two-party vote in South Dakota. The results of the Crosstab model for Trump are thus 1.3 percentage points above the combined PollyVote in South Dakota.
