Afterwar succession
Constitutional foundation for United States presidential line of succession were Article II, Section 1, Section 3 of the 20th Amendment (1933), and the 25th Amendment (1967).

In March 2077, prepared for a nuclear or biological attack from China, the President and the Enclave retreated to remote sections around the globe and make contingency plans for continuing the war.
 * One of the few old world organizations to survive the Great War was the Enclave - before the war the shadow government within the legal government of the United States. Members of the Enclave were hardliners who both embraced the idea of a nuclear war and knew that the common man could not survive it. They believed that as long as the “important people” of the United States survived, they could regroup quickly and wipe out communism once and for all. Enclave used Poseidon Energy facilities - protected during the firestorm of 2077.
 * In 2241 NORAD was offline, there was the large Crater in 2253.
 * Status of the Enclave President position was questioned by Brotherhood of Steel. Their representative in San Francisco (Matthew) referred Dick Richardson as "so-called Presedent".
 * In 2277 there were no U.S. government presence at Pentagon building, however somewhere on the Capital Wasteland area once again Enclave was present.
 * The federal government may not have ever considered the Vaults as society's best chance for survival - the government may have considered themselves the best candidates for rebuilding the world and already had their asses covered in the event of a nuclear or biological war by relocating to other remote installations across the nation (and elsewhere) that weren't necessarily Vaults. The Enclave certainly didn't seem to be devoting much effort to digging up any other vaults and trying to use the human stock there to rebuild civilization.

Executive branch
In year 2220 Congressman Richardson was elected president for the first term of five, through aid and political pressure by his father, previous the U.S. president. It is not certain, if present in year 2241 president Dick Richardson was one elected in 2220, however it was possible (eg. he could had some term off, or terms were longer then four years).

The Cabinet was addresse of the Project report from United States Chemical Corps and Power Plant Operations report from Atomic Energy Commission. Its seat was Executive Office on the oil rig.The only known cabinet level administration officer in the Enclave was Vice-President, the first person in the presidential line of succession. Very likely Cabinet present in the Enclave was minimally staffed.

Agencies present after the War:
 * Secret Service (USSS) - it is not certain, if USSS was an official part of the Enclave armed forces.
 * Atomic Energy Commission (AEC) with unknown exact status, it reported to the Cabinet.
 * National Aeronautics and Space Administration (NASA) mentioned by Vice President Bird ; there was no significant means and resources to do anything serious connected with space affairs on the oil rig; in real world NASA is independent agency created in 1958,
 * Environmental Protection Agency branch in California (no human staff, no the Enclave presence).

Notice: Enclave Patrols at Navarro perimeter had some border police attitude.

Legislative branch

 * According to U.S. Constitution the Vice President of the United States shall be President of the Senate . Vice President was present on the Enclave oil rig.

According to Fallout Bible:
 * 2215 August 1 - Congressman Richardson was rising to power within the Enclave, aided by pressure from his father, President Richardson.
 * 2220 March 5 - Congressman Richardson was elected president for the first term of five.

Judical branch
No information about this branch, except the fact, that court martial was performed by Armed Forces officers (part of executive branch).

Government after destruction of the Enclave oil rig
The destruction of the Enclave's Oil Rig, following the Chosen One’s assassination of the Enclave’s U.S. President and the destruction of their Poseidon oil tanker headquarters off of the California coast, erased all trace of President Dick Richardson from history. However, some broken remnants of the Enclave survived.

Known Enclave officials who could be present after the Oil Rig destruction, would be mainland outposts senior staff or sgt. Granite, if left alive. Additionally, some Enclave personnel might have evacuated in vertibirds before the rig's destruction and some might be deployed on outside missions.

The remaining Enclave forces, led by Colonel Augustus Autumn as an acting commander of the United States Armed Forces, were ordered to relocate to the East Coast of the United States, to the Raven Rock base, by a new President - John Henry Eden. Before destruction of the Oil Rig, Eden was an advisor to US Presidents of the Enclave.

Initially, the only person who knew that Eden was an AI was Colonel Autumn. However, in 2277, Colonel Autumn rebelled against President Eden and revealed his AI identity to the rest of the Enclave members.
