Sarah Palin's Alaska finale: The campaign ad wraps up - Sarah Palin's Alaska - Salon.com: This week's episode served as the final episode in the 8-part marketing presentation that brilliantly defined Sarah Palin as a political brand while simultaneously putting the nail in the coffin of her presidential ambitions. It seemed like a good idea I suppose -- using the ruse of an Alaskan documentary to produce a long-form political ad -- but even her most hardcore fans must have had a hard time buying the Mama Grizzly crap that she was selling. And she never stopped selling it to the bitter end.
