This article provides evidence how the health care plan violates the tenth amendment by saying, "Unless the editorial board can point to the specific powers granted to the general government in the Constitution, any health care solutions should rightly come through the states." It's interesting how this amendment can go in favor of the states when the ninth amendment affirms a similar ruling to the people.
This cartoon shows a child excited to get her license because the tenth amendment says she can. However, the states say she can not get her license until she reaches a specific age. Many rulings fall in this gray area because although they are not listed in the Constitution, they are decided upon by the state.
