The way I understand it is: Obamacare health mandate = federal. Vehicle insurance = state. A state can mandate health insurance; the U.S. government cannot. Of course, Obama, et al., continue to do many things “the U.S. government cannot” do — and he is never thwarted. Hence, we have a dictatorship.
Good point. The Constitution specifies what powers the federal government has over the states and the people. Requiring health insurance was NOT a part of those powers granted to the federal government by the Constitution. Obama decried that the constitution had "negative powers" meaning that it restricted the powers of the federal government.
