Somebody is sending out political text messages, without any identification, that are considered "smear attacks" against the Democrat.
Problem is, these messages seem to be sent BY the Democrat's campaign and his supporters, and Rick Boucher's Congressional office -- in official capacity -- is then claiming the Republican's campaign sent them. What is clear is that the Republican, Morgan Griffith, has categorically denied knowing anything about these messages or being involved with them in any way.
It's one thing to point out your opponent's bad actions.
It's quite another to do them yourself solely to blame him for them.
