The District of Columbia is a blanket of blue on the electoral map, but the 2010 Democratic primary for mayor revealed some cultural and racial divides that are as sharp as any of the states south of the Potomac.
Mayor Fenty won all the white areas and ran well in Capitol Hill, Georgetown, Woodley Park, Cleveland Park, and Tenleytown. Mayor-elect Gray won all the black areas and ran well in Anacostia (particularly Ward 8) and Northeast. The battleground neighborhoods were U Street, Shaw, and downtown.
I don't know enough about Gray to provide an educated analysis of his constituency, but I do know that Fenty represents the white-collar, socially liberal wing of the Democratic Party. He is perhaps known best for riding his bike around the city and hiring Michelle Rhee to scrap the failed programs and entrenched interests in the school system. These are winners with the new, white-collar, professional class in D.C., but I'm not sure they're too popular with old-school District residents.
I would have loved to see a Fenty/Gray poll of Democrats at Nationals Park. My guess is that Nats fans are the kind of white-collar professionals who support Fenty, and the residents who disparage the stadium for its taxpayer-funding and design to reinvent a neighborhood are Gray voters.
