The Crosstab model published an updated forecast of the election result. It currently forecasts a two-party vote share of 39.4% for Clinton, and 60.6% for Trump in South Dakota. In comparison, on October 30 Trump was predicted to collect 60.5% of the vote.
Putting the results in context
In general, however, you should not have too much faith in the results of single models, as they often incorporate large errors. At the very least, one should examine how a model's results compare to benchmark forecasts.
Comparison to the combined PollyVote
The current PollyVote anticipates Trump to gain 59.1% of the two-party vote in South Dakota. PollyVote currently predicts Trump to gain 1.5 percentage points less compared to the results of the Crosstab model.
