If you don’t like the speech you are hearing, it’s easier to ban it, than respond to it. This seems to be behind the attempt to bring back the "Fairness Doctrine," by the Democratic controlled Congress.
Liberals have failed dismally in the battle of ideas in the media. "Air America," (which ironically was the name of the CIA-Operated airline during the Vietnam War), has filed for bankruptcy. Generally, Liberal Commentators have lower ratings than their Conservative opponents. They can’t seem to figure out why, so they blame it on the gullibility of the American public, instead of their bankrupt policies and lack of humor. You may not agree with Rush Limbaugh, but you have to admit he can be hilarious.
When the only sources of over the air News were the three Television networks you might argue the Constitutionality of "The Fairness Doctrine," now with a plethora of information outlets, it is an obvious violation of the freedom of speech guaranteed by the 1st amendment.
