Palin's five book tour goals

Send a message to the establishment

Palin has never been close to establishment elites and has a rocky relationship even with Republican Party leaders. And there are few signs that she needs their affirmation to remain relevant.

The book tour gives her an opportunity to flaunt that independence, as well as flex her political muscle by attracting huge, friendly crowds that will serve as a reminder of her popularity.

With each stop at one of the many Borders or Barnes & Noble she will visit, Palin is likely to remind the political establishment of her remarkable ability to attract crowds and create buzz—and why neither party can afford to ignore her.
