1. The model accuracy was 93.33% (35 states in training set/15 states in test set).
Built a predictive model looking at 4 factors from each state in the election: % of female voters, % of college educated voters, % of non-white voters, and % of 18-29 voters. Visual below shows feature importance of each factor in order of importance
