Black votes matter. If Republicans could get 20 percent of black votes, the Democrats would be ruined. This is highly unlikely, given the approach used by Republicans. However, the point is that Democrats must not only continue to get nine-tenths of black votes, they also need to get a high turnout of black voters on Election Day.
People who expected the election of President Barack Obama to lead to racial healing and a post-racial society failed to take account of the political reality that racial healing and a post-racial society would, at a minimum, reduce black voter turnout.
Black votes matter to many politicians — more so than black lives. That is why such politicians must try to keep black voters fearful, angry, and resentful. Racial harmony would be a political disaster for such politicians.
Racial polarization makes both the black population and the white population worse off, but it makes politicians who depend on black votes better off.
