Charge: As Ismail K. White and Chryl N. Laird note, collectively more than 80% of African Americans self-identify as Democrats according to surveys, and no Republican presidential candidate has won more than 13% of the Black vote since 1968. This is true despite the fact that at the individual level many African Americans are increasingly politically moderate and even conservative. Against this backdrop, what explains the enduring nature of African American support for the Democratic Party? In Steadfast Democrats: How Social Forces Shape Black Political Behavior, White and Laird answer this question by developing the concept of “racialized social constraint,” a unifying behavioral norm meant to empower African Americans as a group and developed through a shared history of struggle against oppression and for freedom and equality. White and Laird consider the historical development of this norm, how it is enforced, and its efficacy both in creating party loyalty and as a path to Black political power in the United States. On the cusp of perhaps the most consequential presidential election in American history, one for which African American turnout was crucial, we asked a range of leading political scientists to assess the relative strengths, weaknesses, and ramifications of this argument.
