Taking advantage of recent thinking about leading economic indicators,
an electoral outcome model is constructed that allows for much earlie
r prediction than found in current models. The model is built in three
stages. First, electoral outcome is expressed as a function of econom
ic performance and voter approval in the manner of current forecasting
models, although a different measure of economic performance is used.
Second, economic performance and voter approval are modeled as functi
ons of new economic bellwethers. Third, the products of steps one and
two are combined in a simultaneous equation system that captures the i
ndirect effects of the bellwethers on electoral outcome, permitting ye
ar-ahead forecasts of presidential elections that accurately predict o
utcomes except when random exogenous events such as the Kennedy assass
ination intervene.
