she's not allowed to earn money ? She's hot right now, if she's gonna make a ton of cash now is the time.

Not to mention she's basically too busy fighting the Usurpers slime machine, she's better off leaving office in Alaska , she can't get anything done while constantly fighting all kinds of fabricated lawsuits the left keeps throwing at her , all because they fear her.
Don't worry, she will return just in time to kick the dems asses in 2012.No matter how much you hate her, she has a huge following, and doing the book tour will help her politics. and get her name out to even more people.
