Slate editor (and CP alum) Josh Levin has the scoop:

As I left my apartment in the Adams Morgan neighborhood of Washington, D.C., this morning…I spotted a more famous Obama supporter: D.C. Mayor Adrian Fenty. The mayor extended his hand, smiled, and asked if I was going to vote. When I responded in the affirmative, he asked, “Barack Obama?” After saying something inarticulate like, “Uh, OK,” I went in and cast my ballot. By the time I emerged, Fenty had disappeared. That’s when I realized that the mayor had been standing directly between two signs prohibiting electioneering in the area.
