The Crosstab model provided an updated forecast of the election outcome. It currently forecasts a two-party vote share of 40.2% for Clinton, and 59.8% for Trump in South Dakota. In comparison, on October 27, Clinton was predicted to end up with 40.5% of the vote.
Putting the results in context
As a general rule, however, don't have too much faith in the results of single models, as they can incorporate large errors. Instead of trusting the results from single models, one should look at combined models or, even better, the combined PollyVote forecast that relies on forecasts from different methods, each of which draws upon different data.
The Crosstab model in comparison with PollyVote's prediction
