Sarah Palin lost her defamation case against the New York Times — the latest in a long line of public battles that most people would have walked away from years ago. Failed elections, a lawsuit that dragged on for years, political doors that kept closing — and through all of it she never once asked anyone for sympathy. She has signaled she still wants to serve, still wants to fight, still has something left to say — and the woman standing there saying it looks more at peace and more certain of herself than she has in years. Some people get quieter when life keeps hitting them. Sarah Palin gets louder.
