The HBO film "Game Change," airing tonight, does an impressive job of creating sympathy for Sarah Palin in its portrayal of the 2008 Republican presidential campaign. It presents her VP run as a slow-motion car crash that represents what's wrong with our electoral process. The question is: Who's looking for such a thing? Palin's a political Rorschach blot, such a divisive figure that when her supporters and detractors discuss her, it's easy to believe they're talking about two entirely separate people.
