The Jerome model enters the econometric models component of the PollyVote. It currently forecasts a two-party vote share of 46.2% for Clinton and 53.8% for Trump in Mississippi. In comparison, on April 26 Trump was still predicted to gain 54.8% of the vote.
Putting the results in context
In general, however, you should not have too much faith in the results of single econometric models, because they may incorporate large errors. Rather than trusting the results from single econometric models, one should use combined econometric models or, even better, the combined PollyVote forecast that relies on different methods and data.
