XM Satellite Radio [XMSR] officials said their satellite radio service this Wednesday will debut XM America Left, a new talk-radio channel dedicated to “progressive” political viewpoints. America Left’s daily program schedule will include such on-air personalities as Al Franken, Jeanene Garofalo, hip hop artist Chuck D of the group Public Enemy and Robert Kennedy, Jr. The America Left complements XM’s more conservative on-air programming that features Bill O’Reilly, Sean Hannity, Michael Savage and Ann Coulter.
