The DeSart & Holbrook model is captured in the econometric models component of the combined PollyVote. The model currently predicts a two-party vote share of 63.0% for Clinton, and 37.0% for Trump in Rhode Island.
Putting the results in context
As a general rule, however, you should not have too much faith in the results of single models, as they may incorporate large errors. Rather, one should check how a model's results compare to benchmark forecasts.

The most recent PollyVote forecasts Clinton to gain 60.9% of the two-party vote in Rhode Island. The results of the DeSart & Holbrook model for Clinton are thus 2.1 percentage points above the combined PollyVote in Rhode Island.
