List of Presidents of the United States (1983: Doomsday)

The United States has had in its history three constitutions, but only two outline the position of a chief executive to serve as head of state and head of government. Below are a list of presidents from the original United States and the Post-Doomsday American Provisional Administration, as well as the Provisional United States, which was the eventual successor to the original USA. Their constitution is considered the third constitution of the USA, as in 2010 the Provisional United states declared themselves the legal successor of the USA, following the demise of the APA in 1995.

Franklin D. Roosevelt was the longest serving President, having been elected to four terms but dying shortly into the fourth. George H.W. Bush, the final president, served the second longest having finished out the remainder of Ronald Reagan's term - extended by officials an extra four years - and being elected outright to two of his own before dissolving the office halfway through his second full term. 

In the chaos following Doomsday, it was deemed not possible to hold elections as scheduled in 1984, and Bush was named President until the next elections by surviving military and civilian officials, tentatively set for 1988.

Bush would win a term of his own right in the 1988 elections, and a second term in 1992. Those involved deemed this possible, and regarded the 1983-1988 period as an semi-unelected continuation of Reagan's second term, thus allowing it under the 22nd amendment to the Constitution, which would have prohibited Bush from running in 1992 otherwise. The public went along with this at the time, deeming it a good idea given the situation - though this has caused dissension in later years, given the events of 1995.

List of Presidents under the Constitution of 1991

#	Name	Took Office	Left Office	Party	Vice President(s)
1	Raymond "Ray" Hunkins1	1992	2001	Republican	Allen Kolstad
2	Mike Sullivan	2001	2005	Democrat	Richard H. Stallings
3	Wayne Allard	2005	2013	Republican	Mike Simpson
4	Mike Simpson	2013	Current	Republican	Sam Brownback

¹ Provisional President prior to being inaugurated in 1993.

When the then Provisional United States ratified their constitution in 1991, a Presidential election was scheduled for the following year. Aside from the reform of the electoral college and the end of the appointment of electors, the Presidency remains unchanged from the 1787 constitution. Both Hunkins and Allard have served two terms, tied for most under this Constitution. Three of the Presidents are members of the Republican Party, with one Democrat, and one served as Vice President before being elected President.

At the time of Doomsday, former Presidents Gerald Ford and Richard Nixon both resided in southern California. Given that no information on either man has ever been found, it is reasonable to assume both men perished either during or after Doomsday. Experts suspect that both, even had they survived, would be deceased by the present day irregardless.
