Tenth Amendment - State's Rights

With Obama's government interfering with states rights in the Arizona illegal immigration case, Obama's health care mandates, etc., I wondered how states were reacting in response. I came across this 2009 article: "At least 35 states have introduced legislation this year (2009) asserting their power under the Tenth Amendment to regulate all matters not specifically delegated to the federal government by the Constitution."
