Short version: If this is a normally licensed song (almost certainly true) and the McCain people paid the BMI, ASCAP or SESAC royalties, then no, there isn’t a dang thing they can do about it.
That said, screw ‘em — find another theme song, why give these hags money?
I’d keep using the song (I personally don’t like it) if they pay the royalties. Send a special check they know comes from the RNC, make them cash it knowing where it comes from. Maybe they’ll burn it in one of their wiccan ceremonies.
Thank you. EXACTLY!
