Mendelson will take his oath as chairman Thursday evening. (Sarah L. Voisin — The Washington Post)

We must be awfully special, because we’re having a heckuva lot of special elections these days. Thursday morning, the D.C. Board of Elections is set to certify the results of the Nov. 6 election, and Thursday evening Phil Mendelson will officially vacate his at-large D.C. Council seat as he becomes Chairman in full. So in less than two weeks, Democratic Party members will pick an interim replacement pending a special election to be held sometime in the spring — the third D.C. special election in two years. As Tim Craig reports in Thursday’s Post, the field will contain plenty of familiar names. Former at-large candidates Sekou Biddle, A.J. Cooper, Patrick Mara and Peter Shapiro all say they are entertaining runs, and soon-to-be-former member Michael A. Brown says he’s under “enormous pressure” to give it another shot.
