The DeSart model released an updated forecast of the election outcome. It currently forecasts a two-party vote share of 62.6% for Clinton and 37.4% for Trump in Massachusetts.
Putting the results in context
As a general rule, however, a good strategy is to not have too much faith in the results of single econometric models, as they sometimes contain large errors. Rather, one should check how a econometric model's results compare to benchmark forecasts.
