The DeSart & Holbrook model is part of the econometric models component of the combined PollyVote forecast. It currently predicts a major vote share of 62.4% for Clinton, and 37.6% for Trump in Rhode Island.
Putting the results in context
As any other method, models are subject to bias. In general, you should not put too much trust in the results of a single econometric model. Rather, one should examine how a model's results compare to benchmark forecasts.
Results compared to the combined PollyVote prediction
The latest PollyVote forecasts Clinton to gain 60.1% of the two-party vote in Rhode Island. The results of the DeSart & Holbrook model for Clinton are thus 2.3 percentage points above the combined PollyVote in Rhode Island.
