The Crosstab model is captured in the econometric models component of the combined PollyVote forecast. It currently forecasts a major vote share of 65.8% for Clinton, and 34.2% for Trump in Massachusetts. In comparison, on November 5, Clinton was predicted to collect 65.9% of the vote.
Putting the results in context
As any other method, models are subject to bias. Thus, as a general rule, you should not put too much trust in the results of a single econometric model. Instead of relying on results from single models, research in forecasting recommends to use combined models or, even better, a combined forecast that incorporates forecasts from different methods, each of which draws upon different data.
The Crosstab model compared with PollyVote's forecast
The most recent PollyVote predicts Clinton to gain 65.2% of the two-party vote in Massachusetts. The results of the Crosstab model for Clinton are thus 0.6 percentage points above the combined PollyVote in Massachusetts.
