The DeSart & Holbrook model enters the econometric models component of the combined PollyVote forecast. According to the model, Clinton will collect 50.4% of the two-party vote share in Iowa, while Trump will win 49.6%.
Historically, Iowa has been a purple state, in which neither the Republican Party nor the Democratic Party has had overwhelming support to secure that state's electoral college votes. This is the reason why predictions in this state are of particular interest.
Putting the results in context
Single models often contain substantial errors, which is why they should be treated with caution. At the very least, one should check how a model's results compare to benchmark forecasts. The most recent PollyVote predicts Clinton to gain 50.4% of the two-party vote in Iowa.
