Article 10 of our Bill of Rights gives the states any power not given to the central government as stated in the U.S. Constitution. It also says that if the same Constitution does not forbid states from exercising certain powers then the states and the People have right to exercise those powers.
So why is the federal government telling people they must buy health insurance? It should be up to the states to vote in their legislatures for such medical laws. The representatives in the state legislatures are there to "represent" the People. It is up to the People to have the final word through their chosen representatives.
In the U.S. Congress, the House of Representatives is more or less made of this type of law making group. Except...the Representatives are there to vote for a much larger group of People than in the state legislatures. There is a better chance of misrepresentation in in U.S. Congress than in any state group.
As for the Senate...that group is far removed from representing the home state People. They have a better chance of voting for certain interests. This is where Barack Obama made his bed and kept the sheets tucked in tight! He made his deals and got the health care bill passed...far from the consent of the People.
It's wonderful how an unrealistically strong central government works. Congress listened to a socialist president and ignored the People. Thankfully the People have a voice using their vote to usurp the power and give it back to the states and the People.
