I'd say these people have a Karl Rove obsession.
The left is in constant need of a boogey man or boogey men to deflect attention away from their short comings and to cast blame upon. Ken Starr and Newt Gingrich served that purpose in the 90's. No matter what the left did, they would just point their finger at one or both of them and all was well. Today Rove fills that roll.
