The DeSart model is captured in the econometric models component of the PollyVote. The model currently predicts a two-party vote share of 62.1% for Clinton and 0.0% for Trump in South Dakota.
Putting the results in context
Individual econometric models should be interpreted with caution, because they may contain substantial errors. Rather than relying on results from single econometric models, the evidence-based approach is to rely on combined econometric models or, even better, a combined forecast that draws upon forecasts from different methods, each of which draws upon different data.
Results vs. other econometric models
In comparison to the average results of other econometric models Clinton performed better with 0.0 percentage points, while Trump did worse with 0.0 percentage points.
