The Crosstab model is included in the econometric models component of the PollyVote forecast. It currently predicts a two-party vote share of 46.4% for Clinton, and 53.6% for Trump in Missouri.
Putting the results in context
As any other method, models are subject to bias. Hence, you should not have too much faith in the results of an individual econometric model. At least, one should check how a model's results compare to benchmark forecasts. The most recent PollyVote foresees Trump to gain 53.6% of the two-party vote in Missouri.
