The Jerome model is captured in the econometric models component of the combined PollyVote. According to the model, Clinton will garner 55.2% of the two-party vote share in Maine, while Trump will win 44.8%. In comparison, on August 16, Clinton was predicted to gain only 44.8% of the vote.
Putting the results in context
As a general rule, however, a good strategy is to not have too much faith in the results of single models, as they may incorporate large errors. Instead of relying on results from single models, research in forecasting recommends to consult combined models or, even better, the combined PollyVote forecast that uses different methods and data.
