At the very least, they ARE violating journalistic ethics.
In the past months 3 members of the Romey campaign, John Bolton, Jay Sekulow, and Walid Phares have all been appearing on Fox news, criticizing Obama, and promoting Romney, without it ever being indicated that they actually work for Mitt Romney.
And while this likely violates federal election laws, nothing will be done. In no small part because the Federal Election Commision has effectively ceased to exist- it is currently deadlocked with 3 members leaning liberal, 3 conservative, with several members currently serving past their terms- because the republican controlled house as refused to move forward on any new appointments to the commission, effectively allowing this election to be the most corrupt in history, with no legal ramifications.
And while on the subject of Fox’s lack of ethics- it is worth noting they have been agressively promoting Karl Roves super pac American Crossroads, more often then not with no mention of its connection to Rove, nor of his connection to Fox. That’s right, Karl Rove, one of the great masters of dirty politics, whose super pac is distributing record amounts of money this year. The super pac which is using loopholes to hide where tens of millions of dollars are coming from, despite the Supreme Courts majority decision in “Citizens United” clearly stating that ALL donations were to be a matter of public record.
