How Congress Violates the Constitution

Congress voted on the health care bill yesterday and it passed by 7 votes.  One of the things that the bill states is that health care insurance must be purchased.  But in the Constitution under Article 1 Section 8 (which outlines the powers of Congress), Congress is not granted the power to mandate health insurance.

Congress refused to call a convention even when over 500 state requests were made asking for a convention to make proposals for the amendments.  In the Constitution under Article 5, it says that if we want to propose amendments, the states must ask Congress to do so, but Congress ignores the states' requests.
