Kenyan R. McDuffie's mayoral campaign highlights blue-collar roots and business backing in D.C. race

Kenyan R. McDuffie reminds voters often that he used to deliver mail — an homage to his blue-collar roots, and to the opportunity that turned his life around.

The Postal Service offered solid pay and benefits, taking him from a neighborhood scarred by the crack epidemic to a law degree and a career in politics.

Backed by the city's business class, he's pitching opportunity for the District's downtrodden — and arguing he has the experience to deliver it.
