Ann Geddes doesn't want a "fair and balanced" workout. But the 49-year-old worker for a nonprofit agency is having no luck getting the channel changed in front of her favorite rowing machine at a Columbia gym. The television happens to be tuned permanently to Fox News. Geddes, a liberal Democrat and former legislative aide to a Howard County delegate, said she can't stomach the conservative lineup that appears nightly as she gets her exercise. Even though the sound is off, the words scrolling across the bottom of the screen infuriate her.
