Various gun rights advocates and organizations, such as former governor Mike Huckabee, former Congressman Ron Paul, and Gun Owners of America, say that an armed citizenry is the population's last line of defense against tyranny by their own government. This belief was also familiar at the time the Constitution was written. The Declaration of Independence mentions "the Right of the People to alter or to abolish" the government, and Abraham Lincoln's first inaugural address reiterated the "revolutionary right" of the people. A right of revolution was not explicitly mentioned in the Constitution; instead, the Constitution was designed to ensure a government deriving its power from the consent of the governed. Historian Don Higginbotham wrote that the well-regulated militia protected by the Second Amendment was more likely to put down rebellions than participate in them.
