The Issue-index model is included in the index models component of the PollyVote forecast. According to the model, Clinton will garner 55.1% of the two-party vote share, while Trump will win 44.9%.
Putting the results in context
As any other method, index models are subject to bias. Hence, a good strategy is to not focus too much on the results of a single index model. Rather than relying on results from single index models, the evidence-based approach is to use combined index models or, even better, a combined forecast that incorporates forecasts from different methods, each of which incorporates different data.
Comparison to other index models
Looking at an average of index models, Clinton's two-party vote share is currently at 53.8%. This value is 1.4 percentage points lower than respective numbers in the Issue-index index model.
Results compared to the combined PollyVote prediction
The current PollyVote foresees Clinton to gain 53.5% of the two-party vote. The results of the Issue-index model for Clinton are thus 1.6 percentage points above the combined PollyVote.
