Evil Twin Booking, a West Philly-based talent agency, has been inundated with e-mails and phone calls related to its representation of former Weather Underground radical Bill Ayers. Gov. Sarah Palin has recently ramped up criticism of Sen. Barack Obama's ties to Ayers, who, along with his wife, Bernardine Dohrn, and other members of the radical group bombed various government buildings in the '70s. Obama and Ayers, now a University of Illinois professor, served on a nonprofit foundation's board together and Ayers once hosted a party for Obama. We're told that Evil Twin Booking/Lost Film Fest partners Scott Beibin and Liz Cole have received more than 1,000 e-mails and tons of calls in recent days with everything from interview requests to attack letters accusing the pair of aiding and abetting terrorists. Evil Twin books speaking engagements with Ayers, his wife and several other Weather Underground members and others including actor Ed Begley Jr., authors and filmmakers. Beibin and Cole declined comment yesterday.
