On his MSNBC show Hardball for May 13, Chris Matthews gleefully attacked Goveror Sarah Palin for hiring a ghostwriter for her upcoming book deal. In like fashion, Mark Silva of the Chicago Tribune’s The Swamp Blog has also gotten into Laugh-at-Palin’s-book mode so you can bet that this will be the scoff du jour among the left-media. But, the thing that proves the Old Media’s hypocrisy and partisanship is this “collaborator” angle. The media are going nuts that Palin is working with what is essentially a ghostwriter — though an upfront one, not a hidden one — and acting as if this is somehow unusual. But it simply is not.
