Things have changed since 1987. Back then conservative talk programs were just coming on to the scene in a big way. The Fairness Doctrine back then most likely would have benefitted conservatives. Not so today, 25 years later.
That doesn't matter. I don't oppose the Fairness Doctrine because it would harm conservatives, I oppose it because it would harm liberty and is inconsistent with the First Amendment. That was as true in 1987 as it is today, and the fact that it would have politically benefitted conservatives was no excuse for supporting it. Either we defend the Constitution or we don't, and supporting an unconstitutional policy because it would help "our" side is about as far from defending the Constitution as you can get.
