HC Reform Update from Mark Sanna: A Florida judge could on Monday become the second judge to declare President Barack Obama's health care reform law unconstitutional, in the biggest legal challenge yet to federal authority to enact the law. The judge, Roger Vinson of the U.S. District Court in Pensacola, Florida, was expected to rule on a lawsuit brought by governors and attorneys general from 26 U.S. states, almost all of whom are Republicans.
