Oh, this one's easy. MSNBC hosts that openly shilled, on the air, for political candidates:
"I felt this thrill going up my leg. I mean, I don't have that too often." - re: an Obama speech
"No. You know I've been criticized for saying he inspires me and to hell with my critics!" - re: Obama
Rachel Maddow: (Democrat shilling rather than specific candidate shilling):
That, this evidence that you, that we have before us here in you, manifested in Bill Wolff, this phenomenon, being fired up like that, that is the key to the most important thing going on in American politics right now, I am convinced. This weekend Congress is going to be in session, this weekend! On a Saturday! We heard it as breaking news last night during this show, Senate Majority Leader Harry Reid announcing that he is not letting the Senate go home, the Democratic leadership is keeping the Senate in Washington over the weekend, because the thing that we have been talking about, the thing that they have been fighting about for months now is finally going to happen, tomorrow, on the weekend. Senate Democrats are finally going to do it. They are finally going to go through with this vote that they've been trying to psyche themselves up for on the Bush tax cuts.
This one isn't shilling, but man, you can't disagree that there's bias here:
"In short, in Scott Brown we have an irresponsible, homophobic, racist, reactionary, ex nude model, teabagging, supporter of violence against women, and against politicians with whom he disagrees. In any other time in our history this man would have been laughed off the stage, as an unqualified, and a disaster in the making by the most conservative of conservatives. Instead the Commonwealth of Massachusetts is close to sending this bad joke to the Senate of the United States."
