D.C. Mayor Adrian Fenty’s biggest event just three days before the Democratic primary was the opening of a dog park in Northwest, which won’t likely dispel the perception that he favors whiter portions of the city over its blacker sections.

Polls and interviews over the last month have shown that the District’s electorate is deeply divided along racial lines over the choice of the city’s next mayor. Black voters are breaking heavily for Fenty’s challenger D.C. Council Chairman Vince Gray, largely because they perceive the mayor as caring more about opening dog parks in white neighborhoods than about unemployment in black neighborhoods.
