I'm having a hard time deciding whether the letter is more remarkable for its stupidity or its irony or the utter audacity of its premise. It claims we've created the impression that our protest was "somehow originated by, affiliated or associated with, connected to and/or approved by Citizens United - which it is not." That's the stupid part. Anyone looking at the online petition or the Facebook page can clearly see that this effort was organized by the Wisconsin Democracy Campaign and is protesting the Supreme Court's decision in Citizens United v. Federal Election Commission, not the special interest group itself.
You can read the group's entire response here.
