The DeSart & Holbrook model is captured in the econometric models component of the PollyVote. According to the model, Clinton will receive 43.7% of the two-party vote share in South Carolina, while Trump will end up with 56.3%.
Putting the results in context
In general, however, a good strategy is to not have too much faith in the results of single models, as they can contain large errors. Instead of trusting the results from single models, forecasting research recommends to rely on combined models or, even better, a combined forecast that relies on different methods and data.
The DeSart & Holbrook model compared with PollyVote's prediction
The current PollyVote anticipates Trump to gain 54.4% of the two-party vote in South Carolina. The results of the DeSart & Holbrook model for Trump are thus 1.9 percentage points above the combined PollyVote in South Carolina.
