The Jerome model is captured in the econometric models component of the combined PollyVote. It currently predicts a two-party vote share of 55.1% for Clinton, and 44.9% for Trump in Maine. In comparison, on October 12, Clinton was predicted to achieve 55.2% of the vote.
Putting the results in context
In general, however, you should not have too much faith in the results of single models, because they may incorporate large errors. Instead of trusting the results from single models, you should consult combined models or, even better, the combined PollyVote forecast that uses forecasts from different methods, each of which uses different data.
Comparison to the combined PollyVote
The latest PollyVote expects Clinton to gain 55.4% of the two-party vote in Maine. PollyVote currently predicts Clinton to gain 0.3 percentage points more compared to the results of the Jerome model.
