Heading into Wednesday night, PBS Executive Editor Jim Lehrer was expected to moderate his 12th presidential debate with a firm hand. But that is not what debate watchers saw him do. Chris Wallace and Chris Matthews criticized his hands-off approach to the candidates, as did Laura Ingraham and Bill Maher. Lehrer was compared to the NFL replacement refs and to Big Bird, after GOP nominee Mitt Romney said he loved the "Sesame Street" character but would stop subsidizing PBS.
