"the use of a recorded song at rallies or public events should never be inferred by any intelligent person as an endorsement by the artist who recorded the song. We chose this song because we like it and felt that the song itself was reflective of our image and campaing theme, and we have paid the appropriate licensing fees for legal use of the song without any discrimination against the artist over his political views."
Nope ASCAP, BMI, SESAC, etc. are facilitators and nothing more. The Rights are owned by whomever holds the publishing, music and lyric rights. ASCAP just collects the performance and radio/TV fees and issue checks to the rights holders for such.
