Regarding the April 6 Metro article “ ‘A tight group’ of Fenty supporters makes up much of Bowser’s circle”:

D.C. Council member Muriel Bowser (Ward 4) and her team should analyze the results from the April 1 Democratic primary more carefully. And she should not downplay the possible challenge from council member David A. Catania (I-At Large) in the fall.

First, turnout for the primary was very low, an indication that Ms. Bowser was too bland to energize voters. Ditto for Mayor Vincent C. Gray (D), but let’s be clear: Ms. Bowser won because Ronald C. Machen Jr., the U.S. attorney for the District of Columbia, torpedoed Mr. Gray’s chances. Before Mr. Machen’s news conference on businessman Jeffrey E. Thompson’s plea, during which he implicated the mayor in the illegal 2010 “shadow campaign,” Mr. Gray was leading Ms. Bowser. It was only after the U.S. attorney stepped in that the tide turned.

Ms. Bowser and her team did not win the election on their own. That credit goes to Mr. Machen.
