I want to know the answer to the following question:
What has the doctrine of incorporation been used to ensure?
All the background I'm provided with is that "While it has not been fully implemented, the doctrine of incorporation has been used to ensure, through the Due Process Clause and Privileges and Immunities Clause, the application of most of the rights enumerated in the Bill of Rights to the states.". Is that enough to answer the question?
Answer: yes
