Sarah Palin is a phenomenon:

Sarah Palin is a singular national industry. She didn’t invent her new role out of whole cloth. Other politicians have cashed out, used the revolving door, doing well in business after doing good in public service. Entertainment figures like Arnold Schwarzenegger, Jesse Ventura, and even Ronald Reagan have worked the opposite angle, leveraging their celebrity to make their way in politics. And family dramas have been a staple of politics from the Kennedys—or the Tudors—on down. But no one else has rolled politics and entertainment into the same scintillating, infuriating, spectacularly lucrative package the way Palin has or marketed herself over multiple platforms with the sophistication and sheer ambitiousness that Palin has shown, all while maintaining a viable presence as a prospective presidential candidate in 2012.

The numbers are staggering. Over the past year, Palin has amassed a $12 million fortune and shows no sign of slowing down. Her memoir has so far sold more than 2.2 million copies, and Palin is planning a second book with HarperCollins. This January, she signed a three-year contributor deal with Fox News worth $1 million a year, according to people familiar with the deal. In March, Palin and Burnett sold her cable show to TLC for a reported $1 million per episode, of which Palin is said to take in about $250,000 for each of the eight installments.
