Jonah, if they take “Unfiltered” off the PBS airwaves, after it just debuted last June, it tells me one thing: the chat about moving the PBS lineup to the center is over. It was just another ploy to sway GOP legislators to the belief that the channel isn’t all “Frontline” all the time. Granted, the Moyers show “Now” has been cut from 60 minutes to 30, and without Moyers, it has to be less obnoxious. But Tucker’s show was never going to match Moyers for invective, and mild-mannered host aside, Tucker’s guest list was 50-50 in its ideological divide at best. All the fulminating about right-wing PBS bias from the Media Matters types is going to look even more empty.
