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).
Federalist No. 67
Unless the President commits a major crime or dies, they are present in the White House for the entirety of the four years. Several American citizens are challenging the standards; they are fighting for a way to enable the United States to re-elect presidents when necessary - maybe after two years. Research has shown a pattern that displays almost half of the support for presidents typically dies down after the first half of the term. On the contrary, others argue that a single six-year term would benefit the country as whole. Without the pressure of campaigning for a reelection, having a longer term would allow the President to strictly focus on national and global issues. These two perspectives provide alternatives to the US Constitution's original plan for the executive branch that Hamilton backed in Federalist 67.
