McCain threatened to sue.
Mike Riggs got a hold of Red State's lawyer's reply, which is like-stupendous, totally:
[T]he subject matter of your letter is a fairly obvious parody to any person of even barely functional literacy. Thus – and your client probably didn’t tell you this – even she recognized that the posts were parodies (or “parody’s,” as she put it). At approximately 8:25 p.m. EDT on September 17th, your client posted to her Twitter feed, “I don’t care about parody’s(sic) or fake names – but falsely putting my name on someone else’s writing is illegal.” She then subsequently deleted this Tweet, presumably when someone told her that “parody’s” were constitutionally protected and it might look bad in a subsequent lawsuit if she were caught admitting in public that these posts were obvious parodies. Not to worry: My client has screenshots.
(I treat as obvious humor the assertions in your letter that the parodies in question were appropriations of your client’s likeness for advertising purposes, and that persons with no minimum contacts at all with California would in any way be susceptible to jurisdiction there. It is my sincere suggestion that your client do so as well.)
My client will not be bullied out of exercising his First Amendment right to make clear his belief that your client is a spoiled, brainless twit who is cheapening the political discourse in this country. Therefore, henceforth, the “Totally Meghan McCain” series may be found at http://pajamasmedia.com for your client’s reading pleasure.
On the off chance that your client actually files the baseless litigation you threatened in your September 23, 2011 letter, Mr. Wolf will pursue all available remedies available under any applicable anti-SLAPP statutes, State law malicious prosecution/abuse of process actions, and/or Rule 11 sanctions. Although I do not envy you the Herculean task before you, please make sure your client understands the potential consequences to her personally – in addition to those her attorney would face – for pursuing this ill-advised course of action.
