All of these folks — plus three — made the cut. (Mike DeBonis/The Washington Post)

So long, Michael Green, Luis I. Poblete, Frank Sewell and Octavia Wells: We hardly knew ye. Those four D.C. Democrats were among the 13 who picked up ballot petitions for the April 1 mayoral primary, but they all failed to turn in signatures by Thursday’s deadline. So we’re left with nine candidates — incumbent Vincent C. Gray, plus challengers Carlos Allen, Muriel Bowser, Christian Carter, Jack Evans, Reta Jo Lewis, Vincent Orange, Andy Shallal and Tommy Wells — though that list could be culled further though petition challenges. The upshot is that this year’s Democratic primary is the most wide-open since at least 1998, when several D.C. Council members and a bow-tied bureaucrat named Anthony A. Williams vied to replace Marion Barry. More from Loose Lips and WAMU-FM.
