Does higher voter turnout consistently benefit the Democratic Party in American national elections? Daron R. Shaw and John R. Petrocik examine the long-standing assumption that low turnout suppresses Democratic performance, utilizing extensive electoral data from the late 20th and early 21st centuries. The authors argue that the relationship between turnout and partisan outcomes is far more complex and often weaker than conventional political wisdom suggests.

Political scientists frequently cite this work as a critical challenge to the 'turnout myth' that dominates campaign strategy. Experts note that the book provides a rigorous empirical foundation for understanding why mobilization efforts do not always yield the expected partisan dividends.
