The DeSart & Holbrook model is part of the econometric models component of the combined PollyVote forecast. It currently forecasts a two-party vote share of 65.5% for Clinton, and 34.5% for Trump in California.
Putting the results in context
As any other method, models are subject to bias. Therefore, as a general rule, you should not have too much faith in the results of an individual econometric model. Rather, one should examine how a model's results compare to benchmark forecasts.

The latest PollyVote expects Clinton to gain 62.7% of the two-party vote in California. The results of the DeSart & Holbrook model for Clinton are thus 2.8 percentage points above the combined PollyVote in California.
