The DeSart model is captured in the econometric models component of the PollyVote forecast. It currently forecasts a two-party vote share of 37.9% for Clinton and 0.0% for Trump in Rhode Island. In comparison, on August 4 Trump was predicted to collect 37.9% of the vote.
Putting the results in context
As any other method, econometric models are subject to bias. Therefore, as a general rule, one should not be overly confident the results of an individual econometric model. Rather than trusting the results from single econometric models, research in forecasting recommends to use combined econometric models or, even better, the combined PollyVote forecast that uses forecasts from different methods, each of which uses different data.
Comparison to other econometric models
When compared to the average results of other econometric models Clinton performed worse with 0.0 percentage points, while Trump did better with 0.0 percentage points.
