The DeSart model published an updated prediction of the election result. The model currently predicts a two-party vote share of 50.6% for Clinton, and 49.4% for Trump in Iowa.
In Iowa, the popular vote is usually decided by a narrow margin. This is why the state is commonly regarded as a swing state, which makes it particularly interesting from a forecasting perspective.
Putting the results in context
Single models should be treated with caution, because they may incorporate large biases. At the very least, one should check how a model's results compare to benchmark forecasts. The latest PollyVote forecasts Clinton to gain 50.6% of the two-party vote in Iowa.
