What is the most widely held ideal of the US political culture?

belief in a limited government that protects individual liberties

belief in a unitary government and centralized decision making

belief in a strong government that monitors individual actions

belief in a weak central government and strong local governments

I believe the answer is: The Belief in a limited government that protects individual liberties

Limited government that protect individual liberties mean that the majority of power that exist within a country is held by the citizens, not the people. The role of the government is solely to prevent other Citizens from harming each others' liberties.
