On CNN's Newsroom today, Don Lemon hosted a segment with Princeton Julian Zelizer on what Lemon sees as the apparent presidential ambitions of Hillary Clinton and Ted Cruz. "I just think they're running," offers Lemon.

The entire peice is an excercise in overt media bias. It actually opens with the two men laughing at the clip of Cruz.

Lemon and Zelizer establish quickly that Hillary has "all but declared," and then move on to the focus of the segment - a discussion about what is wrong with Cruz.

The professional newsman, Lemon, offers his guest this jumping off point:

I think what many people find disengenous about ted cruz is that they think that this whole thing with the debt ceiling, with Obamacare, with shutting the government down was really just to elevate his profile so that he can, just to elevate his profile so he can run for president.

This sets Zelizer up to offer a completely left-wing view of the situation.

Well yeah. I mean, Hillary Clinton can use his... her experience as a way to promote what she's about. What she's done in government is a reason to be excited about her. I think many people feel about Senator Cruz that what he's done in government might be exactly why he shouldn't be president. That he's kind of used the process as a way to just make a name for himself.

And how does the veteran, unbiased newsman respond to this plainly partisan analysis? Does he challenge Zelizer's assertion that what Clinton has done in government "is a reason to be excited about her" by probing her vulnerabilities over Benghazi or her mishandling of the Arab Spring?

No. He simply agrees with Zelizer and moves on to the next overtly biased segment.
