The Issue-index model is included in the index models component of the PollyVote forecast. According to the model, Clinton will obtain 56.6% of the two-party vote share, while Trump will end up with 43.4%. In comparison, on October 12 Trump was still predicted to win 43.8% of the vote.
Putting the results in context
Single index models can contain large biases, and should be treated with caution. Rather than trusting the results from single index models, you should look at combined index models or, even better, a combined forecast that uses forecasts from different methods, each of which draws upon different data.
Results in comparison to other index models
If we look at an average of index models, Clinton's two-party vote share is currently at 53.7%. Compared to numbers in the Issue-index index model Clinton's index model average is 2.9 percentage points lower.
Results compared to the combined PollyVote forecast
The current PollyVote predicts Clinton to gain 53.8% of the two-party vote. PollyVote currently predicts Clinton to gain 2.8 percentage points less compared to the results of the Issue-index model.
