An interview with government professor John J. Pitney Jr., author of The Art of Political Warfare, will air at 8 a.m. on Sunday, July 27 as the lead item on CBS Sunday Morning. Interviewed by CBS News Correspondent Jerry Bowen, Pitney will provide expert commentary about the ongoing California recall effort, a fixture of both local and national media coverage this summer. "People in states without direct democracy have wondered how it would work in California," said Pitney.
