Yesterday, Burnt Orange Report unmasked prolific commenter "Buck Smith" as actually being Dave Beckwith, a Cornyn staffer who evidently splits his time between working in Cornyn's federal Senate office and on the Cornyn campaign. The Cornyn campaign has defended Beckwith, saying he is simply doing the same thing everyone else on blogs is doing, although having a legitimate reason for using a pseudonym is a bit different than using one because you are a paid political operative.
Beckwith, however, didn't just comment at one or two blogs (Burnt Orange Report and DailyKOS being two most people are aware of). In fact, he trolled sites belonging to mainstream media outlets, and sockpuppeted across nearly a dozen Texas-based and national blogs.
Many political mistakes are blamed on staff error. But sometimes the fault lies with -- staff error.
