The DeSart & Holbrook model is captured in the econometric models component of the PollyVote forecast. The model currently predicts a two-party vote share of 42.1% for Clinton, and 57.9% for Trump in Indiana.
Putting the results in context
As any other method, models are subject to bias. Therefore, as a general rule, you should not be overly confident the results of a single econometric model. Instead of trusting the results from single models, we recommend to consult combined models or, even better, the combined PollyVote forecast that includes forecasts from different methods, each of which draws upon different data.
Results compared to the combined PollyVote forecast
The current PollyVote expects Trump to gain 57.1% of the two-party vote in Indiana. The results of the DeSart & Holbrook model for Trump are thus 0.8 percentage points above the combined PollyVote in Indiana.
