Florida's attorney general has questioned the constitutionality of the federal healthcare bill, and is calling on states to study whether to file suit to kill a provision requiring that individuals buy health insurance or pay a fine. William McCollum, a Republican who is running for governor in 2010, said that the fine might be illegal because, in his view, it is disconnected from any commercial act. The attorneys general of South Carolina and nearly a dozen other states have also threatened to sue over the mandate, the New York Times reports.
