The Crosstab model is captured in the econometric models component of the combined PollyVote. According to the model, Clinton will obtain 49.1% of the two-party vote share in Iowa, while Trump will win 50.9%. In comparison, on October 31, Clinton was predicted to win 49.5% of the vote.
Historically, Iowa has been a swing state, in which neither the Democrats nor the Republicans have had overwhelming support to secure its electoral college votes. Hence, predictions here are of particular importance.
Putting the results in context
Individual models may contain substantial biases, and should be interpreted with caution. Rather, one should check how a model's results compare to benchmark forecasts.
