The Issue-index model published an updated forecast of the election result. It currently predicts a two-party vote share of 56.6% for Clinton, and 43.4% for Trump.
Putting the results in context
As any other method, index models are subject to bias. As a result, you should not have too much confidence in the results of an individual index model. Instead of trusting the results from single index models, the best practice is to consult combined index models or, even better, a combined forecast that relies on forecasts from different methods, each of which relies on different data.
Comparison to other index models
If we look at an average of index models, Clinton's current two-party vote share is at 54.2%. Relative to numbers in the Issue-index index model Clinton's index model average is 2.4 percentage points lower.
