Brent Bozell looks at Helen Thomas’ claim that there are no vocal liberals in the media here.  

According to Helen,

“Hell, no!” she thundered. “I’m dying to find another liberal to open their mouths [sic]. Where are they?”

Bozell replies with a long laundry list of vocal liberals in the media: 

Dan Rather predicts Big Oil will try to manipulate the election for
John McCain: “The people who can affect the price of oil would prefer a
Republican presidential candidate. Watch the price of oil. If it goes
down, which it may very well, it could help John McCain quite a bit.”

With a straight face, retiring New York Times reporter Linda Greenhouse
claims, “President Clinton played to the center, not the left, in
selecting Ruth Bader Ginsburg and Stephen G. Breyer.” … NBC labels
the late Jesse Helms an “outspoken ultra-rightist,” but waxed about
Howard Metzenbaum as a “populist” who “always fought for the little
guy.”

Michelle Obama is off limits, but not Cindy McCain: 

In reference to John McCain’s wife Cindy, New York Times reporter
Alessandra Stanley writes: “As the Equal Rights Amendment faded as a
cause and conservatism made a comeback, Republican spouses became ever
more careful to stay three steps behind their men and the times.” 

And my all time favorite, a liberal who does see bias in the media: 

CBS’s Katie Couric sees bias now: “However you feel about her politics,
I feel that Sen. Clinton received some of the most unfair, hostile
coverage I’ve ever seen.”
