"Experts said that the decision would immediately cut into one of the Democratic Party’s critical financial advantages in television advertising."

"That’s because federal law requires that television broadcasters give political candidates low advertising rates, but extends no such requirement to super PACs, which are often charged double, triple and even four times as much for the same television time. Republicans in recent election cycles have been more reliant on super PACs and national party committees than Democrats, whose candidates have tended to out raise Republicans and who therefore often have been able to take advantage of the lower television ad rates. Allowing unlimited coordinated spending between candidates and parties would essentially permit both to take advantage of the lower rates...."
