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).
2014 New York gubernatorial election
It was believed that the Republicans would nominate someone who was not up for re-election in 2014 and so did not have to give up their office to run, and who would use the campaign to raise their profile for a more competitive statewide bid in the future. Rob Astorino, the Westchester County Executive and the only Republican to enter the race, was not up for re-election until 2017. Business magnate and television personality Donald Trump flirted with a run, but decided against it, instead running for president as a Republican in 2016 and winning. Other potential candidates who did not run were former U.S. Representative Vito Fossella, Dutchess County Executive Marcus Molinaro and businessman and 2010 candidate for New York State Comptroller Harry Wilson.
