The Jerome model published an updated prediction of the election result. The model currently predicts a major vote share of 53.3% for Clinton, and 46.7% for Trump in California. In comparison, on August 16, Clinton was predicted to win only 46.7% of the vote.
Putting the results in context
In general, however, you should not have too much faith in the results of single models, since they sometimes incorporate large errors. Instead of relying on results from single models, the recommended strategy rely on combined models or, even better, the combined PollyVote forecast that incorporates different methods and data.
The Jerome model in comparison with PollyVote's prediction
The latest PollyVote anticipates Clinton to gain 60.0% of the two-party vote in California. The results of the Jerome model for Clinton are thus 6.7 percentage points below the combined PollyVote in California.
