16,000 proposals to change the Constitution:
33 approved by Congress to be voted on by the states.
27 approved.
Very difficult to do.
Yes it is difficult as it should be. If it was easy the constitution would cease to exist.
The real hell of it is many cases should not even reach the supreme court. It should be handled at the state level. An expansive federal government has reached deep into the states via activist federal courts deciding things they should not be involved with.
