My guess if some one digs into it, you will find the 0 2012 campaign is behind this transparent political smear job.
Look at the accusations. The smears are all calculate to drive a wedge between Palin and the "tea party". About the only smear they DID not put into it was "Sarah Palin had a lesbian affair". This smear job will not work with the real tea party, but it is carefully designed to discredit Palin with the caricature of the tea party the crazy Left thinks exists.
Supposedly, in wacko Leftist land, the tea party is a bunch of racist intoleratnet old white purtains waving bibles and buring crroses. so they send out this slime bag to write a book that will punch all the supposed "hot button" issues of their imaginary tea party folks.

Bertelsmann is no ordinary German corporation. Via the foundation and the foundation’s yearly budget of some €70 million, it is a major player in German politics and European politics more generally. “
