The Jerome model published an updated forecast of the election outcome. It currently forecasts a two-party vote share of 42.8% for Clinton and 57.2% for Trump in Arizona.
Putting the results in context
Single econometric models should be regarded with caution, because they may incorporate large biases. At the very least, one should check how a econometric model's results compare to benchmark forecasts.
Results compared to the combined PollyVote forecast
PollyVote currently predicts Trump to gain 54.1% of the two-party vote in Arizona, which is 3.1 percentage points below the results of the Jerome model.
