How did the transition from the activism of the 1960s to the conservatism of the Reagan-Bush era affect African American politicians?

Carl Stokes was the first black mayor of a major American city. In 1967, Stokes ran for mayor of Cleveland for the second time and defeated his opponent, Seth Chase Taft, the grandson of former president William Howard Taft.
Stokes started his mayoral term during a time of great change in the midst of both the radical Black Power movement and a civil rights movement defined by its non-violent approach. Stokes's major accomplishment as mayor was to open up city jobs to black people. Stokes's term was also marked by the outbreak of race riots, which occurred throughout the nation in the late 1960s, and the loss of tax revenue to the city as a result of white flight—that is, the fleeing of white property owners and business owners to suburbs.
I would argue that many black politicians, particularly mayors, remained activist well into the 1980s. What markedly changed over the years was the federal approach to tackling cities' problems. In the 1960s, President Lyndon B. Johnson instituted the Great Society, with the intention of eradicating poverty and giving lower-income citizens a better quality of life. In the 1980s, President Ronald Reagan's policies, particularly his fervent support of drug wars, were deemed detrimental to inner cities.
Former Atlanta mayor Maynard Jackson, served Atlanta from 1974–1982 and again from 1990–1994. In the 1980s and early 1990s, Atlanta suffered from high crime rates, particularly as a result of drug wars. Both a declining tax base and hardline federal policies towards drugs, which attacked both dealers and users with ferocity, led to an erosion within communities and limited black mayors' abilities to foster progress.
The rhetoric about inner cities during the Reagan era, particularly perceptions of black and Latino people, made it more difficult for the public to foster sympathy for the plights of those who succumbed to addiction or crime. On the other hand, in the 1960s, before the election of President Richard Nixon in 1968, there remained a sense that the government had a responsibility to assist those who were living with the problems of poverty and crime.
