Interesting analysis! Especially in the context of our discussion about the press. Do you think Kos is right, and the press really is looking away from the most important story? Why would they do that? Corruption? Incompetence?
Extreme partisanship is incompatible with the appearance of neutrality. Therefore it's problematic to present an article developing the idea that the biggest story is that Republicans are a bunch of whores getting paid to spread propaganda for money. You absolutely don't have to believe this, but my experience is that many reporters are committed to being as fair as possible. They also want to get the facts right. And if they fail, they write corrections. Do you think politicians come anywhere close to this standard?
Reporters get paid because it's their job. If they work for an openly partisan media outlet, they will write articles with a partisan slant. But if they're a
major middle-of-the-road daily, network or cable news outlet, they will take pains to present "both sides." They can find people who will say that the problem is that Republicans have become irredeemable scum-suckers, but then they feel duty-bound to find someone to present the " other side." And they will find people who say that's all wrong, it's the Democrats who are irredeemable scrum-sucking whores. So you end up with a "he said, she said" story, which doesn't illuminate anything. And that's unsatisfying for both the writer and the reader.
Kos is just venting. They know very well why major news outlets are ignoring the so-called story.
I haven't actually read the piece, though. Just going by excerpts.
A critic is entitled to believe that the mainstream news media is biased, but I hope they check their own preferred outlets for signs of bias as well. I'm not naive enough to say that everyone in the MSM wants to be fair, but a lot do. It's part of their own deep idealism.
The real bias IMO is not conservative vs. liberal. It's more that the media is biased toward sensationalism, conflict and drama. They want ears, eyeballs and clicks. Like most businesses, they want metrics to assess if they are executing their business plan. I grew disenchanted with CNN's wall-to-wall Trump coverage a long time ago, but when it comes to direct quotes or excerpts from documents, it's usually OK.
There's no easy fix for that potential problem except to practice a certain amount of skepticism. Check what other outlets are saying. Get a less-filtered view from C-SPAN. Seek out sources that aren't so U.S.-centric. Try the PBS News Hour for a more in-depth treatment. Etc. A lot of people aren't going to bother, but some will.
