Looking back over it, the worst thing about Kenneth Vogel’s pointless failed effort at a smear job is that he doesn’t tell us who turned him on to this non-story. The only interesting fact here is that someone appears to have tried to convince Vogel and The Politico that there was something scandalous about the German ambassador to the US attending a campaign event even though, as Vogel verified, nothing improper happened. So who tried to convince him? A GOP operative? A Rival campaign? Maybe neither. Maybe Vogel and his editors were dumb enough to dream this crap up on their own.
