The DeSart & Holbrook model is captured in the econometric models component of the combined PollyVote forecast. It currently predicts a two-party vote share of 66.4% for Clinton, and 33.7% for Trump in Massachusetts. In comparison, on October 22, Clinton was predicted to collect only 65.3% of the vote.
Putting the results in context
As any other method, models are subject to bias. Therefore, as a general rule, don't rely too much on the results of an individual econometric model. At least, one should check how a model's results compare to benchmark forecasts.
Comparison to the combined PollyVote
The current PollyVote expects Clinton to gain 64.2% of the two-party vote in Massachusetts. PollyVote currently predicts Clinton to gain 2.2 percentage points less compared to the results of the DeSart & Holbrook model.
