Does anyone know what NewsBusters is complaining about?

I marvel sometimes at the versatility of the crack bias hunters over at NewsBusters. Even though they've spent the better portions of their careers failing to make sense and embarrassing themselves, they still manage to come up with new and inventive ways to look completely foolish. Take, for example, Brent Baker's latest complaint that ABC World News anchor Charles Gibson “had time to convey President Barack Obama's praise of Edward Brooke for 'breaking barriers' as the first popularly-elected black U.S. Senator, but not to inform viewers he broke that barrier as a Republican.”

OK, I'm feeling generous -- if Baker wants to argue that ABC should have identified Brooke as a Republican, that's fine. One could just as easily argue that Brooke's accomplishment transcends parties and politics. But then Baker goes on to note that Brooke was “a fairly liberal Republican,” and in case you're not a regular reader of the blog, NewsBusters really, really hates liberal Republicans and they get very mad when the media fail to ID such Republicans as “liberals.” So Baker is upset that ABC didn't identify as Republican someone who, by virtue of his liberalness, would otherwise be treated as a leper by his blog.

But then it gets even dumber.

Here's the context in which Baker characterized Brooke as a “fairly liberal Republican”:

Neither Gibson nor [NBC's David] Gregory pointed out that after two terms representing Massachusetts, in 1978 Brooke, a fairly liberal Republican, was challenged and beaten by one of the media's liberal heroes, the late Paul Tsongas -- a Democrat who was a white guy.

Can anyone explain to me how Paul Tsongas' whiteness is at all relevant here? What is he implying -- that Massachusetts voters in 1978 were racists for voting out a black Republican? That Tsongas himself was a racist for challenging a black Republican? I seriously can't figure it out, and Baker offers no explanation.

And this is what passes for media criticism on the right.

So yeah, it's dumb. Perhaps not as dumb as Matt Lauer's terrorist neckwear, but still pretty dumb.
