I didn't read her book(s?), so I don't know if her positions on specific issues, like dealing with the illegal aliens, are included there. I haven't listened to or read much of any of her speeches since '08, and I don't Twitter. What I'm saying is I don't know where she stands on many things, although others probably do, and the reason for this is I will not be disappointed again like I was with GW, ever, and so I'm not disenheartened that Palin isn't running because I don't "know" her.
I don't know, either, that she's "what/who we need" while a great many others believe she is, in spite of the virulent and senseless hatred of her by yet another group.
Just to speculate, it may be that she's not running precisely because that hatred will galvanize opposition in just the way we cannot afford in '12.
