Remember that Marion Barry was re-elected to the Washington City Council overwhelmingly dispite his multiple drug arrests, some in the Mayor's Office. Charlie Rangel won re-election with 91%% off the vote. In twenty voting districts in Philadelphia and 9 in Chicago, Romney did not get a single vote.
Minorities don't care about unemployment, budgets or deficits, or Bengazi, or the Keystone Pipeline, they vote strictly on race. OJ Simpson could have been elected.
