The Issue-index model is captured in the index models component of the PollyVote. It currently predicts a major vote share of 55.1% for Clinton, and 44.9% for Trump.
Putting the results in context
Single index models can contain large errors, which is why they should be treated with caution. Instead of relying on results from single index models, forecasting research recommends to use combined index models or, even better, the combined PollyVote forecast that draws upon different methods and data.
Results in comparison to other index models
