NEXT WEEK, Air America Radio debuts its around-the-clock radio station of the left. Al Franken will play the marquee role, filling the noon-to-3:00 p.m. slot. Daily Show co-creator Lizz Winstead will run the morning program with Public Enemy rapper Chuck D. And comedienne Janeane Garofalo will be punching the clock at 8:00 p.m. Opening Day is March 31.

Which raises a good question: Why don’t they just wait 24 hours and do the launch on April Fool’s Day?
