Can anyone blame her? McCain allowed her to be marginalized in '08 when it appeared his ticket might win. Then, her own party either directly or through surrogates went on, along with the Liberals, on a spree of character assassination. In the forefront was and is the GOPs Joseph Goebbels, Carl Rove.
I disagree with her decision, but I don't blame her. And it's not her own party, it's the GOP, and she's not a true republican. Sarah Palin is a true American, and if there is a conflict between country and party, she will side with our country. That's why the Beltway GOP can't stand her.
