Just to follow on from my post from this morning, here's yet another article that would easily have fit in on Newsbusters, except that its chief source of quotes is a liberal who is complaining about the partisan nature of CNN's political coverage:

When Clinton supporter Lanny Davis appeared on CNN during primary night, shortly before 10 p.m., there was a peculiar exchange with host Anderson Cooper.

Cooper: Lanny, let me start off with you. We haven't heard from you tonight. Your take on Barack Obama's speech earlier?
Davis: You haven't heard from me tonight. And I'm not sure — I’m not sure you want to hear from me tonight but —
Cooper: We heard from Paul Begala. This is your big chance.
Davis: Well, actually, I don't think we heard very much from Paul Begala. We did hear an awful —
Cooper: All part of the conspiracy against Hillary Clinton, I suppose.

During the Election Night broadcast, there was palpable tension between Davis and CNN reporters and panelists on camera — and apparently, with producers off camera.

Looking back, Davis said by phone this afternoon, he considers it “the worst experience I ever had on television.”

What bothers Davis most is that CNN is the network with which he’s had the longest relationship, where he’s maintained close friendships through the years, and that he's always considered middle-of-the-road in its coverage. But in his opinion, CNN has not treated Hillary Clinton fairly in the ’08 race.

Formerly special counsel to President Bill Clinton, Davis admits wholeheartedly to being a partisan and strongly supports Clinton against Obama.

So what happened on Tuesday night?

Davis, by his account, was invited to appear on the CNN panel in New York but declined because of a family commitment — his son’s baseball practice in Maryland. Instead, he opted to participate by remote from the network’s D.C. studio.

He was instructed to arrive around 8:30 p.m., he said, in order to take over the pro-Clinton position once Paul Begala left. So Davis left the baseball practice early in order to arrive at the studio on time, but he didn’t make it on air until almost 10 p.m.

A CNN spokesperson said that Davis was scheduled to go on-air at 9pm, but CNN didn't go to him or any commentator during Sen. Obama's speech in the 9pm hour, just as no commentators were on-air during Sen. Clinton's speech later the same night.

Davis said he told a producer several times before getting on-air that he wanted to offer a counterpoint to CNN’s panel, which he thinks is too pro-Obama.

Regarding the panel's make-up, Davis said that he believes Gloria Borger, David Gergen, Donna Brazile and Carl Bernstein are all tougher on Clinton than on her rival. And he maintains that Roland Martin is definitely a “partisan for Obama.” (Martin has not official endorsed Obama and is not labeled as such on the network,)

More from Davis:

Regarding CNN’s competitors, Davis said that MSNBC is “shameless about their bias toward Obama,” and Fox has been the fairest — which is saying a lot coming from a self-described member of the Democratic Party’s left wing.

“Fox, no matter how much you might criticize an ideological bent, in this campaign, they have been religiously middle-of-the-road, point-counterpoint,” Davis said.

And that’s what Davis said he expects from CNN, the network where he’s had “the longest history, best friends, and most respect.”
