From a January 12 BigJournalism.com entry by James Hudnall:

When the news broke yesterday that Sarah Palin had signed on as a Fox News contributor an awful shrinking feeling in the groin must have hit the execs at the network's competitors. While the old media continues to try to paint her as a crazed redneck, the fact of her ascendancy as a serious power player is now an inescapable fact. Her autobiography, Going Rogue is a publishing phenomenon, having sold 2.7 million copies as of December 1 of 2009. It's one of just four political memoirs to sell more than a million copies.
