Though Brazilians of at least partial African heritage make up a large percentage of the population, few blacks have been elected as politicians. The city of Salvador, Bahia, for instance, is 80% people of color, but voters have not elected a mayor of color. Journalists like to say that US cities with black majorities, such as Detroit and New Orleans, have not elected white mayors since after the civil rights movement, when the Voting Rights Act of 1965 protected the franchise for minorities, and blacks in the South regained the power to vote for the first time since the turn of the 20th century. New Orleans elected its first black mayor in the 1970s. New Orleans elected a white mayor after the widescale disruption and damage of Hurricane Katrina in 2005.

Beginning with its incorporation in 1802, Detroit has had a total of 74 mayors. Detroit's last mayor from the Republican Party was Louis Miriani, who served from 1957 to 1962. In 1973, the city elected its first black mayor, Coleman Young. Despite development efforts, his combative style during his five terms in office was not well received by many suburban residents.
