It was not your usual subject for an Assembly hearing in the Capitol Building . Yesterday's hearing convened by the Assembly Committee on Health took on the arcane and important subject of adverse selection and risk pools. The nerdy-tech tone of the hearing was not lost on its participants. "I have to applaud the committee -- for taking on such a dry topic," said David Panush, director of government relations for Covered California, the state's health exchange. "But it is so important. I'm really glad to see it."
