Rathergate and bias

The Right Curmudgeon points out there were two way for CBS to play the TANG story. One was the way Mary Mapes put it together. Here is the other:

The second way is the following: a well-connected Kerry fundraiser, Ben Barnes, and other Texas Democrats, are peddling stories about President Bush. They present documents to us, the Killian memos, purporting to show that Bush was given preferential treatment in the TANG in the late 1960s, and perhaps disobeyed orders to get a physical, went AWOL, etc. But our document examiners have some problems with them. And other people are telling us that Killian wouldn't have written something like that, including Killian's widow and son. The documents on their face, viewed objectively, don't pass the smell test... dude, they look like they were printed out on my Dell. What gives? Do the Democrats have a dirty tricks operation? Has someone with connections to the Kerry campaign conspired to perpetrate a federal crime, forgery of government documents, in an effort to influence a Presidential election, not 35 years ago, but right now, in 2004? How high up does the conspiracy go?

This is exactly the problem of bias and sourcing discussed here.
