Jurisdictions

Map

The jurisdictional map relies on a multivariate maximum likelihood model using Census-derived attributes as features for predicting the probability an area will vote in majority for a Republican candidate. The probability of (R) is expressed as a continuous value, along with several of the social and demographic characteristics of each area. The model was trained using election results for the 119th Congress’ districts and projected instead onto jurisdiction.
