There's also, probably, a factor of laziness. Reading some of the MSM's reporting is like reading a "rip-and-read" version of DNC talking points. I wonder how many reporters don't actually do the work of investigating a story, but rely upon the latest propaganda dump from their allies on the left?
Almost all of them.
Their editors are no better. Perhaps worse.
On a national level, nobody in the journalism business is promoting things like legwork, research, investigation...or even the need for accuracy.
Instead, it's all about making the story fit into their template and serve their agenda.
Lazy is the Left's watchword since they replay not only the DNC but Kos et al. The media uses the same framework ala Nam, and other military incursions the USA has made in the last 50 years. In fact, Kennedy , Leahy, et al are using the same lingo they used to help us lose in Nam. Of course, blogs which actually do investigations of new items are a God-send.
My daughter worked at a small local paper at one point. A good portion of what went in was copy/pasted from press releases from one group or other
Reporters like having their work easy. If somebody will hand them a pre-written story, it gives them more time to hang out in the bar. And if they can avoid going out on the street, they feel safer
