Simple method for predicting American presidential greatness from victory margin in popular vote (1824-1996).
The author tested the simple method (SM) for predicting presidential greatness from the winner's victory margin in the popular vote and A. M. Schlesinger Jr.'s (1986) cycles of American political history with the expert sample presidential rankings of W. J. Ridings Jr. and S. B. McIver (1997). The SM, which involves only simple calculations on minimal data available shortly after an election, predicts greatness ratings that are above average for winners with high victory margins in years of public purpose and for winners with low victory margins in years of private interest. Also, the SM predicts ratings that are below average for winners with low victory margins in public purpose years and for winners with high victory margins in private interest years. Based on the data for 42 elections from 1824 to 1996, the SM success rate was 81.0% for all elections, 85.2% for the 27 1st-term elections, 86.2% for elections after 1880, and 94.4% for 1st-term elections after 1880. Chi-square analyses showed all percentages significant at the .001 level.
