Twenty-second Amendment to the United States Constitution
Some argue that the 22nd Amendment and 12th Amendment bar any two-term president from later serving as vice president as well as from succeeding to the presidency from any point in the presidential line of succession. Others contend that the original intent of the 12th Amendment concerns qualification for "service" (age, residence, and citizenship), while the 22nd Amendment, concerns qualifications for "election", and thus (strictly applying the text) a former two-term president is still eligible to "serve" as vice president (neither amendment restricts the number of times an individual can be elected to the vice presidency), and then succeed to the presidency to serve out the balance of the term (though prohibited from running for election to an additional term).
2016 United States presidential election in Wyoming
Following his second term, Barack Obama is not eligible for another reelection. In October 2015, Obama's running-mate and two-term Vice President Joe Biden decided not to enter the race for the Democratic presidential nomination either. With their term expiring on January 20, 2017, the electorate is asked to elect a new president, the 45th president and 48th vice president of the United States, respectively.
