There are several reasons why libs think they can go after radio and not have to worry about TV or the press being affected. The most important is legal precedent. The fairness doctrine was the law of the land and has never been struck down by SCOTUS(only by the now lib dominated FCC). In fact, all rulings by SCOTUS have reaffirmed the doctrine. Next, any attempts at imposing the fairness doctrine on lib dominated TV and press would have to break new legal ground. So radio is fair game to them and tv and press are relatively protected. Which leads to the next thing which is that since SCOTUS has been unclear on where they would land on this, and since any legal case may come after Obama has appointed his judge or judges, its worth a shot. Even if a SCOTUS ruling comes before an Obama appointment to the bench, nobody believes they would extend an anti-fairness doctrine ruling to tv and press. Libs know that the worst that could happen is that we would end up right back at where we are now.
