The Jerome model is captured in the econometric models component of the PollyVote. The model currently predicts a major vote share of 54.3% for Clinton, and 45.7% for Trump in Iowa.
Historically, Iowa has been a purple state, in which neither the GOP nor the Democrats have had overwhelming support to secure its electoral college votes. Therefore, forecasts here are of particular interest.
Putting the results in context
Individual models should be regarded with caution, since they often include large errors. Rather, one should check how a model's results compare to benchmark forecasts.
The Jerome model compared with PollyVote's prediction
The most recent PollyVote forecasts Clinton to gain 50.3% of the two-party vote in Iowa. The results of the Jerome model for Clinton are thus 4.0 percentage points above the combined PollyVote in Iowa.
