I'm glad there's an effort to get more liberals on the radio, but I honestly don't like the way they're going about it. They shouldn't, for the most part, be signing Names, they should be signing people with experience in radio. Radio is a unique medium which takes special skills. 3 hours per day, 5 days per week, is a pretty big challenge.
My only proviso would be to substitute (for liberals) the phrase rigorous, fair-handed skeptical thinkers with a bias toward believing that there is such a thing, nebulous though it might be, as the 'public interest.'
And I assure you, I'd be happy with a Republican if I could find one.
