But let's suppose that the lingering forces of de facto segregation suddenly disappeared. In cities wherein banks lent mortgages to Blacks to buy homes in any neighborhood and owners of apartment buildings rented to Blacks in any neighborhood, Black districts would survive if and only if substantial numbers of the city's Black legal residents choose to continue living in such districts, i.e, if they practiced self-segregation. So consider the observed political advantages of self-segregation.
- Cities with Black wards elect more Black councilmen and are more likely to elect Black Mayors, e.g., Atlanta, Washington DC, Baltimore, and Detroit
- Segregated neighborhoods also enhance the elections of Black county executives, county legislators, state legislators, and U.S. Congressmen. But they are unlikely to enhance the elections of Black governors and Black U.S. Senators.
- It's not surprising that in the last fifty years Black neighborhoods have facilitated the elections of thousands of Blacks to state and local offices, over a hundred Black Congressmen, but only four U.S. Senators -- Edward Brooke (MA 1966), Carol Moseley Braun (IL 1992), Barack Obama (IL 2004), Corey Booker (NJ 2012); two governors -- Deval Patrick (MA 2006, 2010), Douglas Wilder (VA 1990); and one president -- Barack Obama (2008, 2012). (Note that David Patterson was not elected governor of New York; he succeeded Eliot Spitzer when Spitzer resigned in 2008.)
