The Vice President
Second in command, first in the line of succession, and the most constitutionally underutilized job in the federal government.
What Is the Vice President?
The Vice President is the second-highest office in the United States government. They're elected alongside the president as a running mate, voters pick them as a package deal. But once in office, the VP's actual day-to-day role is surprisingly limited by the Constitution. John Adams, the first VP, famously described the job as "the most insignificant office that ever the invention of man contrived."
And yet, the VP is one heartbeat away from the most powerful job on earth. Nine vice presidents have gone on to become president. That single fact makes the office far more important in practice than its formal job description suggests.
Why Does the Office Exist?
The founders created the vice presidency for two practical reasons. First, they needed someone to preside over the Senate , a neutral figure who could manage debate without being a senator themselves. Second, they needed a clear line of succession in case a president died, resigned, or was removed.
The original design was unusual: the person who came in second in the Electoral College became VP. So in 1796, John Adams won the presidency and his opponent Thomas Jefferson became his vice president. This led to obvious friction between a president and a VP from opposing factions.
The 1800 Crisis That Changed Everything
In 1800, Thomas Jefferson and Aaron Burr were running mates , but they each got the same number of electoral votes, throwing the election to the House of Representatives. It took 36 ballots to elect Jefferson. This disaster prompted the 12th Amendment (1804), which required electors to cast separate votes for president and vice president. From that point on, running mates were elected together as a team.
What the Constitution Says

Article II, where the VP is established (Public Domain)
The vice presidency is mentioned in several places in the Constitution, but the actual job description is remarkably brief. The founders gave the VP just one formal duty , presiding over the Senate, and left everything else up to the president and circumstances.
The requirements to become VP are identical to the presidency: at least 35 years old, a natural-born US citizen, and a resident of the US for at least 14 years.
Article I, Section 3
"The Vice President of the United States shall be President of the Senate, but shall have no Vote, unless they be equally divided."
Article II, Section 1
"In Case of the Removal of the President from Office, or of his Death, Resignation, or Inability to discharge the Powers and Duties of the said Office, the Same shall devolve on the Vice President."
12th Amendment (1804)
"The Electors shall meet in their respective states and vote by ballot for President and Vice-President, one of whom, at least, shall not be an inhabitant of the same state with themselves..."
In plain English: The VP runs the Senate but only votes to break a tie. If the president can't serve, the VP takes over. President and VP are elected together on the same ticket.
What Does the VP Actually Do?
The Constitution gives the VP just one real job. But in modern presidencies, vice presidents have taken on much larger roles. Here's how the office actually works today:
President of the Senate
The VP's only formal constitutional duty. They preside over Senate sessions, managing debate, recognizing speakers, and keeping order. In practice, this role is almost entirely ceremonial and is usually handled by the President Pro Tempore or junior senators. The VP only shows up when their vote might be needed.
Tie-Breaking Vote in the Senate
When the Senate is split 50-50, the VP casts the deciding vote. This is rare but hugely consequential. VP Kamala Harris cast a record 32 tie-breaking votes in her term. VP Mike Pence cast 13. A single tie-breaking vote has passed major legislation that shaped the country.
Counts the Electoral College Votes
On January 6th following a presidential election, the VP presides over a joint session of Congress to officially count and certify the Electoral College votes. This is largely ceremonial, but the January 6, 2021 events put this normally routine duty at the center of national attention.
Whatever the President Assigns
Beyond the formal duties, the VP's actual workload is entirely up to the president. Modern VPs lead major policy initiatives, represent the US on diplomatic trips, serve as key advisers, break gridlock in Congress, and serve as the president's most important political ally. Dick Cheney was considered one of the most powerful VPs in history. Others have had much smaller roles.
Be Ready to Be President
The most important unofficial job of any VP. Eight presidents have died in office and one resigned, in each case the VP stepped in immediately. The VP must be fully briefed on all national security matters, have a staff ready to govern, and be prepared to take over on a moment's notice.
The VP and the Senate

The Senate chamber, where the VP presides and casts tie-breaking votes (Public Domain)
The VP's connection to the Senate creates an interesting constitutional quirk: the VP is simultaneously part of the executive branch (elected with the president) and serves as an officer of the legislative branch (presiding over the Senate). This dual role has led to occasional debates about conflicts of interest and separation of powers.
The Tie-Breaking Record
The January 6th Role
Every four years, the VP presides over the joint session of Congress that certifies the Electoral College results. Until January 6, 2021, this was entirely routine and ceremonial. That day brought unprecedented national attention to a constitutional duty most Americans didn't know existed, and raised lasting questions about the VP's role in the certification process.
The 25th Amendment: When Things Go Wrong
Passed in 1967 after the shock of JFK's assassination exposed gaps in the succession process, the 25th Amendment is the VP's most important constitutional document. It spells out exactly what happens when a president can't do their job:
VP Becomes President if the Seat Is Vacant
If the president dies, resigns, or is removed, the VP immediately becomes president, not acting president, but the full president. This has happened eight times in US history.
Filling a VP Vacancy
If the VP position becomes vacant (through death, resignation, or succession), the president nominates a new VP who must be confirmed by a majority vote in both chambers of Congress. Gerald Ford and Nelson Rockefeller both became VP through this process.
President Voluntarily Transfers Power
If the president knows they'll be temporarily unable to serve, such as during surgery, they can send written notice to Congress. The VP becomes acting president until the president sends another letter saying they're able to resume.
Involuntary Transfer of Power
If the VP and a majority of the Cabinet believe the president is unable to perform their duties, even if the president disagrees, they can transmit a written declaration to Congress. The VP immediately becomes acting president. The president can contest it; Congress then has 21 days to decide by a two-thirds supermajority. This section has never been invoked.
The 9 VPs Who Became President
The vice presidency has been called a stepping stone, and the numbers back that up. Nearly one in five VPs has gone on to hold the presidency:

Quick Facts
Where to Find It
Did You Know?
The VP's house wasn't always free
For most of US history, vice presidents had to pay for their own housing in DC. It wasn't until 1974 that Congress designated Number One Observatory Circle as the official VP residence. Nelson Rockefeller was the first VP to live there officially.
Aaron Burr killed Alexander Hamilton
VP Aaron Burr shot and killed former Treasury Secretary Alexander Hamilton in a duel in 1804, while still serving as VP. He was charged with murder in both New York and New Jersey but was never tried. He completed his term.
John C. Calhoun served under two different presidents
Calhoun is the only VP to serve under two presidents from different parties, John Quincy Adams (Democratic-Republican) and Andrew Jackson (Democrat). He eventually resigned to take a Senate seat.
The VP residence has a name
Number One Observatory Circle sits on the grounds of the US Naval Observatory in Washington DC. It was built in 1893 as the home for the observatory superintendent. The VP gets a full staff, security detail, and the house, but pays for their own food and personal expenses.
