To understand and predict Sarah Palin's actions is not all that difficult. Follow the money. Halfway through her term as governor of Alaska, demi-governor Palin resigned. Why? The governor's salary paled in comparison to the seven-figure book deal she nabbed and the prospect of future riches.
But how to maintain the cash-cow of public celebrity? What better way than a faux campaign for the Republican nomination for president? Actually running for office is a cash-burning strategy. That's not what Sarah Palin is about. Having to answer gotcha questions like "What do you read?" isn't on her menu either. Celebrity, notoriety, and most especially money, are. Money is Palin's Blue Plate special, her raison d'être.
Sarah Palin has sacrificed both friends and family on the altar of ambition. The tale of her rise to the governorship of Alaska is a sordid one. But, for reasons that even she may not understand, Palin's real ambition is wealth, her driving force avarice.
