The DeSart & Holbrook model is captured in the econometric models component of the combined PollyVote forecast. The model currently forecasts a major vote share of 44.0% for Clinton, and 56.0% for Trump in Mississippi. In comparison, on October 29, Clinton was predicted to end up with only 43.7% of the vote.
Putting the results in context
Individual models often incorporate substantial errors, which is why they should be treated with caution. Rather than trusting the results from single models, you should rely on combined models or, even better, a combined forecast that uses forecasts from different methods, each of which draws upon different data.
The DeSart & Holbrook model compared with PollyVote's forecast
The latest PollyVote forecasts Trump to gain 55.5% of the two-party vote in Mississippi. The results of the DeSart & Holbrook model for Trump are thus 0.5 percentage points above the combined PollyVote in Mississippi.
