A new poll this week showed Sarah Palin's approval ratings nosediving -- especially among women. It's as if she had been the new guest at a long-running dinner party: at first we were grateful for the new blood and, after oft-repeated tales of fighter pilot heroism and Harvard Law achievement, delighted to hear fresh stories about moose burgers, government jets sold on eBay, boondoggle bridges rejected, and lipsticked pit bulls. But suddenly we couldn't help but notice that the house was on fire. And as amused as they were by all the new stories and new characters, the American people knew that the "Welcome Sarah" party was over. It's time to get serious.
