The Jerome model is captured in the econometric models component of the PollyVote forecast. It currently predicts a major vote share of 86.4% for Clinton, and 13.6% for Trump in Washington, D.C..
Putting the results in context
As any other method, models are subject to bias. Hence, don't have too much faith in the results of a single econometric model. Instead of trusting the results from single models, the evidence-based approach is to rely on combined models or, even better, the combined PollyVote forecast that uses forecasts from different methods, each of which uses different data.
The Jerome model compared with PollyVote's forecast
The current PollyVote forecasts Clinton to gain 90.4% of the two-party vote in Washington, D.C.. PollyVote currently predicts Clinton to gain 4.0 percentage points more compared to the results of the Jerome model.
