Atlanta is perhaps the city with the greatest degree of black political empowerment (BPE) in the United States. Yet in 2009 a relatively weak white mayoral candidate nearly won the general and runoff elections over a field of stronger black candidates. Why? Treating Atlanta as a prototypical case, the article examines factors that undermine the capacity of blacks to retain control of mayoralties in strong BPE cities, with an emphasis on disruptions to black electorates, discontent among black citizens, and reinvestment in electoral politics by whites at the local level.The city that became a post-civil rights movement emblem of the political power held by AfricanAmericans could have a white mayor for the first time in a generation-a possibility that has some in the black community scrambling to hold on to City Hall. (Haines, 2009) The struggle for and substance of black political empowerment (BPE) is a key concern of the urban politics literature. Studies examine the necessary and sufficient conditions for black political incor-). 1 What of the electoral challenges and lessons of retaining blacks in city hall as mayors over time?Other than the cases where black control of city hall was hard-fought but fleeting in non-majority black cities (e.g., Charlotte, Chicago, New York City, Denver, Dallas, and Seattle), scholars know little about the factors for losing mayoral control by blacks. Cases where blacks in BPE cities have lost mayoral control to whites (or other groups such as Latinos), or faced strong competition from non-blacks in biracial elections, are uncommon. In a few cities where BPE has been strong (e.g., Detroit, Memphis, Newark, and Washington D.C.), black mayoral regimes are uninterrupted for two decades or more. New Orleans is the exception because of its dramatic demographic transformations from hurricane recovery and public housing demolition. Nearly uninterrupted black mayoral regimes of a decade or so, with white mayors being electoral stand-ins between black mayoral administrations, have occurred in other strong BPE cities (e.g., Baltimore and Philadelphia).Demographic projections, however, forecast that Detroit, Portsmouth (VA), Newark, Washington, D.C., Richmond (VA), Inglewood (CA), Philadelphia, and other strong BPE cities with black
