After a surprisingly frank comment by former First Lady Barbara Bush, saying she wished Sarah Palin would just "stay in Alaska," the ex-Governor is determined to have the last laugh. I'm told she's itching to crush Barbara's son George's new book 'Decision Points' with the release of her tome, 'America by Heart: Reflections on Family, Faith and Flag.'

"Sarah is super competitive and want's to teach those Bush's a lesson," an insider tells me. "She hates to lose and hates it when the Washington elite put her down. Which is exactly what she thinks the Bush family did to her with that nasty comment."
