Will there be a need for US national elections?
<p>Suppose that the majority of the states decide to elect 1 person as their leader to replace the president.Then will there be a need for national US elections to vote for a president?What exactly will happen?Will there be national elections held even in that case?Who will be the head of the country?</p>

<p>The US presidency operates strictly on four-year terms, which currently begin and end at noon on January 20th of every year that is one more than a multiple of four (for example, the current term began in 2021 and will end in 2025).  There is a national election for the presidency every four years in the last November of each presidential term.  As this fact is common knowledge, I suppose the question is</p>
<blockquote>
<p>Suppose that the majority of the states decide to elect 1 person as their leader to replace the president before the end of a four-year term.</p>

<p>It is certainly possible to remove a president before the expiration of the term of office.  The mechanism provided by the constitution is that of impeachment and conviction.  But any vacancy that may arise during a four-year term for any reason must be filled according to the constitution and any legislation that does not conflict with the constitution.  The constitution and the <a href="https://en.wikipedia.org/wiki/Presidential_Succession_Act" rel="nofollow noreferrer">presidential succession act</a> establish a &quot;line of succession&quot; from which a successor must be chosen essentially by algorithm.  If this <a href="https://en.wikipedia.org/wiki/Presidential_Succession_Act#Table_of_statutory_successors" rel="nofollow noreferrer">fairly long list of people</a> were to be exhausted without filling the office, it would be for congress to make further provisions, though its ability to do so without a president in office is questionable, because enacting legislation requires interacting with the president.</p>
<p>Thus, there is at present no provision for &quot;early elections&quot; as are common in parliamentary systems.  If &quot;the people&quot; came to the consensus that such an election were desirable, it would be possible to call one by <a href="https://en.wikipedia.org/wiki/Amending_the_United_States_Constitution" rel="nofollow noreferrer">amending the constitution</a>, which requires far more than a &quot;majority of the states&quot;; rather, it requires an amendment</p>
<ul>
<li>first to be approved by either
<ul>
<li>a vote of two thirds or more in both houses of congress, or</li>
<li>a constitutional convention called by congress in response to a request by two thirds or more of the state legislatures, and</li>
</ul>
</li>
<li>and subsequently to be approved by the legislatures of three fourths of the states.</li>
</ul>
