On a clear day Robin Williams can see forever — or at least to Alaska, from which Sarah Palin's fiefdom crept souther and souther until going absolutely radioactive this week in St. Paul. Assessing the phenomenon last night on Letterman, Williams alluded to the hard questions in its wake; to wit, how does a mother of five find time to hunt caribou? And what exactly does set a "snow machine" champion like Todd Palin apart from lesser men? It's one of the comic's more inspired tangents of late, and one that reminded us how little the issues really matter when we can conceivably have a vice president who can play wineglasses like Sandra Bullock in Miss Congeniality. This politics thing gets easier for us every day. [CBS]
