The DeSart & Holbrook model published an updated forecast of the election result. It currently forecasts a major vote share of 53.3% for Clinton, and 46.7% for Trump in Colorado. In comparison, on October 22, Clinton was predicted to achieve only 53.2% of the vote.
Colorado is traditionally a purple state, where the Republican and Democratic candidates have historically won similar levels of support among voters. This is the reason why the election outcome in that state is considered important in determining the overall result of the presidential election.
Putting the results in context
As any other method, models are subject to bias. Thus, as a general rule, you should not have too much confidence in the results of an individual econometric model. At the very least, one should examine how a model's results compare to benchmark forecasts.
Comparison to the combined PollyVote
The latest PollyVote predicts Clinton to gain 54.9% of the two-party vote in Colorado. The results of the DeSart & Holbrook model for Clinton are thus 1.6 percentage points below the combined PollyVote in Colorado.
