Abstract

This model generates projections of the national popular vote and Electoral College votes a year in advance of the U.S. Presidential Election, before each party’s nominees are known. It forecasts the Democratic two-party popular vote in each state and the District of Columbia. It uses four independent variables: national head-to-head polling data 13 months prior to the election, the states’ prior election result, a party-adjusted home state advantage dummy variable, and a party adjusted variable simply counting the number of consecutive terms the current incumbent party has occupied the White House. New to this year’s model is a polling average approach that encompasses all possible candidate matchups for whom data is available. This year’s forecast suggests a distinct possibility of an Electoral College misfire benefitting the Republicans.
