In order to demonstrate challenges to conventional wisdom (Aldrich 1980a, b; Bartels 1985 1988; Orren and Polsby 1987), this article develops several forecasting models of the presidential primary vote to compare to a baseline model of the aggregate primary vote (APV) that uses pre-primary and New Hampshire primary data. The models indicate that candidates' Gallup poll position and cash reserves are significant positive predictors of a candidates' primary vote share, though there are differences between forecasting models of the primary vote in Democratic and Republican nomination campaigns. Parallel models incorporating results of the New Hampshire primary improve the predictive power of the baseline model, indicating that the bellwether primary has a "correcting" effect on the relative standings of some candidates seeking a presidential nomination. This effect is substantially greater for Democrats than for Republicans.
