The Jerome model is included in the econometric models component of the combined PollyVote. It currently predicts a major vote share of 43.0% for Clinton, and 57.0% for Trump in South Dakota.
Putting the results in context
In general, however, you should not have too much faith in the results of single models, because they can contain large errors. Instead of trusting the results from single models, we recommend to consult combined models or, even better, the combined PollyVote forecast that includes forecasts from different methods, each of which draws upon different data.
Results compared to the combined PollyVote forecast
The most recent PollyVote expects Trump to gain 58.7% of the two-party vote in South Dakota. PollyVote currently predicts Trump to gain 1.7 percentage points more compared to the results of the Jerome model.
