The DeSart & Holbrook model enters the econometric models component of the combined PollyVote. According to the model, Clinton will collect 50.3% of the two-party vote share in Iowa, while Trump will win 49.7%. In comparison, on October 22 Trump was still predicted to achieve 50.1% of the vote.
In Iowa, the election outcome is usually decided by a narrow margin. Therefore, the state is commonly regarded as a swing state, which makes it particularly interesting from a forecasting perspective.
Putting the results in context
As a general rule, however, don't have too much faith in the results of single models, as they sometimes contain large errors. At least, one should check how a model's results compare to benchmark forecasts.
Results compared to the combined PollyVote forecast
The current PollyVote forecasts Clinton to gain 50.9% of the two-party vote in Iowa. The results of the DeSart & Holbrook model for Clinton are thus 0.6 percentage points below the combined PollyVote in Iowa.
