The DeSart & Holbrook model is included in the econometric models component of the PollyVote. It currently predicts a two-party vote share of 36.8% for Clinton, and 63.2% for Trump in Utah. In comparison, on October 20, Clinton was predicted to win 37.5% of the vote.
Putting the results in context
As a general rule, however, one should not have too much faith in the results of single models, because they may incorporate large errors. At least, one should examine how a model's results compare to benchmark forecasts.
Comparison to the combined PollyVote
The current PollyVote forecasts Trump to gain 59.5% of the two-party vote in Utah. PollyVote currently predicts Trump to gain 3.7 percentage points less compared to the results of the DeSart & Holbrook model.
