The Crosstab model provided an updated forecast of the election outcome. According to the model, Clinton will collect 59.2% of the two-party vote share in Illinois, while Trump will end up with 40.8%. In comparison, on October 31, Clinton was predicted to win 59.7% of the vote.
Putting the results in context
As a general rule, however, you should not have too much faith in the results of single models, as they sometimes contain large errors. Rather than trusting the results from single models, the best practice scientific advice is to rely on combined models or, even better, the combined PollyVote forecast that includes forecasts from different methods, each of which draws upon different data.
The Crosstab model compared with PollyVote's forecast
The most recent PollyVote expects Clinton to gain 59.6% of the two-party vote in Illinois. PollyVote currently predicts Clinton to gain 0.4 percentage points more compared to the results of the Crosstab model.
