(By msnbc's Tucker Carlson)Best question of the night: "How do hedge funds make America a better place?" Brian Williams asked that question of both Hillary Clinton and John Edwards. The correct answer is: They don’t. Yet both candidates dodged it. In other words, John Edwards is running an entire presidential campaign against corporate greed and on behalf of the disenfranchised working man, and he can’t even bring himself to criticize hedge funds, the very symbol of parasitic capitalism run amok. Come on. Best answer of the night: “Yes.” That was Joe Biden’s monosyllabic response when Brian Williams asked him if, in the event he’s elected president, he’d be able to control his compulsive talking. You could see the strain on Biden’s face as he struggled to keep his tongue under control. But he did it, maybe for the first time, and for that he deserves credit. Least believable moment: “Why do Republicans seem so eager to run against you?” Williams asked Hillary Clinton. “Because I’ve stood up for what I believe in,” she answered. In other words, I’m so principled, so steadfast in my views, that my intellectual integrity intimidates my opponents. Ha! Even Clinton’s friends concede she’s politically malleable. Can she really believe this? Maybe she does. People’s capacity for self-deception is endless. Most revealing moment: John Edwards admitted (by not raising his hand) that he has never had a gun of any kind in his house. And he claims to be a Southerner? Most amusing moment: Bill Richardson pledging to get us out of Iraq “with diplomacy” on his very first day in office. On his second day, Richardson promised to solve the energy crisis. Bill Richardson is magic.
