The Crosstab model enters the econometric models component of the combined PollyVote forecast. It currently forecasts a two-party vote share of 49.5% for Clinton, and 50.5% for Trump in Iowa. In comparison, on October 27, Clinton was predicted to win only 49.3% of the vote.
In Iowa, the election outcome is often close. Therefore, the state is commonly regarded as a purple state, which makes it particularly interesting from a forecasting perspective.
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 a single econometric model. Instead of relying on results from single models, we recommend to look at combined models or, even better, a combined forecast that draws upon forecasts from different methods, each of which draws upon different data.
Comparison to the combined PollyVote
The latest PollyVote expects Trump to gain 49.4% of the two-party vote in Iowa. The results of the Crosstab model for Trump are thus 1.1 percentage points above the combined PollyVote in Iowa.
