The Jerome model is included in the econometric models component of the PollyVote forecast. The model currently predicts a two-party vote share of 46.6% for Clinton and 53.4% for Trump in South Carolina.
Putting the results in context
In general, however, you should not have too much faith in the results of single econometric models, because they sometimes contain large errors. Instead of relying on results from single econometric models, the evidence-based approach is to look at combined econometric models or, even better, a combined forecast that incorporates different methods and data.
Comparison to other econometric models
If we look at an average of South Carolina econometric models, Trump's current two-party vote share is at 55.7%. Compared to his numbers in the Jerome model Trump's econometric model average is 2.3 percentage points better.
Comparison to the combined PollyVote
The results are consistent with the prediction from PollyVote for South Carolina.
