“…However, no previous studies come close to evaluating the effect of the percent black district population on electing African American state legislators over such a long period of time (1970s–2010s), and this shortcoming matters since this relationship exhibits significant longitudinal variation. For instance, since the end of the 1960s civil rights movement, southern black enfranchisement has increased (Black and Black 1987; Bullock and Gaddie 2009; Thompson 1982), but as is true of all groups, voter turnout is dynamic (Wolfinger and Rosenstone 1980), and black participation is sensitive to various contextual factors (Brace et al 1995; Fraga 2016a, 2016b; Gay 2001; Hayes and McKee 2012; Keele et al 2017; Keele and White 2019). Additionally, throughout this period most southern whites had come to realign with the Republican Party (Hood, Kidd, and Morris 2012; Valentino and Sears 2005).…”
