Jerome model in Arizona: Trump is in the lead
The Jerome model is included in the econometric models component of the PollyVote forecast. It currently predicts a major vote share of 42.8% for Clinton, and 57.2% for Trump in Arizona. In comparison, on August 16, Clinton was predicted to collect 57.2% of the vote.
Putting the results in context
As any other method, models are subject to bias. Thus, as a general rule, don't focus too much on the results of an individual econometric model. At the very least, one should check how a model's results compare to benchmark forecasts.
Results compared to the combined PollyVote prediction
The most recent PollyVote expects Trump to gain 53.0% of the two-party vote in Arizona. The results of the Jerome model for Trump are thus 4.2 percentage points above the combined PollyVote in Arizona.
