The 15 Most Consequential Vice Presidents, Ranked by the Record

The one real power, counted

The Constitution gives the vice president a single operational power: "The Vice President of the United States shall be President of the Senate, but shall have no Vote, unless they be equally divided." The Senate has kept the ledger since 1789, and it stands at 309 tie-breaking votes (Senate Historical Office, Votes to Break Ties). That ledger is the score column above, and it is the only official number the office produces. Everything else a vice president does, from running a war-powers legal shop to overseeing an 800-billion-dollar stimulus, is delegated by the president and can be withdrawn as easily as it was granted.

The distribution is lopsided and revealing. Kamala Harris cast 33, an all-time record set in barely three years because she governed with a 50-50 Senate and post-2013 rules that let nominations and reconciliation bills pass by bare majority; John C. Calhoun needed nearly eight years to cast his 31 (Time, 2023). John Adams cast 29 when the whole Senate had 26 members and cast the very first tie-breaker in the chamber's history on July 18, 1789 (Senate Historical Office). Meanwhile twelve vice presidents, including Joe Biden and Dan Quayle, never broke a single tie. The number measures the Senate's arithmetic as much as the officeholder's diligence, which is why this ranking treats it as one component and not the whole story. The office reached its 300th recorded tie-break only in December 2023; more than one in ten of all such votes in American history were cast after 2017.

The Mondale template

For most of American history the vice presidency was a parking space. John Nance Garner, who held it for eight years under Franklin Roosevelt, is remembered chiefly for despising it. The office that exists today was designed in December 1976, when Walter Mondale sent Jimmy Carter a memo proposing something no vice president had ever had: general advisory access instead of line assignments, a West Wing office steps from the Oval, a standing private lunch, and full access to presidential paper. Carter accepted all of it (Miller Center). Every subsequent vice presidency, Bush's, Gore's, Cheney's, Biden's, Harris's, operated inside Mondale's architecture. Cheney ranks first because he pushed that architecture to its documented maximum, running energy policy, intelligence review, and war-powers questions from the vice presidency itself. Mondale ranks second because he built the room Cheney worked in.

The transition between the two eras is visible in the ledger itself. Richard Nixon, ranked ninth, was the hinge: Eisenhower gave him real assignments, sent him abroad repeatedly, and left him presiding over the government's visible functions through three presidential illnesses, and Nixon still cast 8 tie-breaking votes on the side (Senate Historical Office; Miller Center). George H.W. Bush quietly cast 7 during the Reagan years, and every vice president since Mondale has kept the West Wing office. The office Garner mocked and the office Cheney ran are separated by a single typed memo and fifty years of precedent hardening around it. That is why a vice president who cast only one tie-breaker outranks four who cast none and two who cast dozens: structure, once built, outlasts the builder.

Cheney and the maximal office

Dick Cheney holds the top rank on a documented portfolio no other vice president has matched, not on Senate math. Within George W. Bush's second week in office in 2001, Cheney was named chairman of the National Energy Policy Development Group, which produced the administration's energy plan after at least ten meetings with industry representatives; his office fought all the way to the Supreme Court to keep the task force's records secret and largely prevailed on executive-privilege grounds (Government Accountability Office; Energy Task Force records). That fight alone made vice-presidential secrecy a constitutional question.

After September 11, 2001, Cheney ran a parallel national-security operation from inside the vice presidency, driving the legal theories behind detention, surveillance, and interrogation policy and staffing his office with lawyers who wrote much of the post-9/11 war architecture (Miller Center). He cast 8 tie-breaking votes, including the one that passed the 2003 tax cut package (Senate Historical Office). The reach was real and the record is public. It is also the case that later administrations partly rolled back the expansive reading of the office he pioneered, which is why this report scores his succession-and-legacy component lower than his influence and portfolio components. Rank one measures how much of the government a vice president actually ran, and by that measure the record is not close.

An office the Framers built backward

The vice presidency began as a design error. Under the original Constitution the office went to the presidential runner-up, which in 1796 saddled John Adams with his chief rival Jefferson as his own vice president, and in 1800 produced an exact electoral tie between Jefferson and his running mate Aaron Burr that took the House 36 ballots to resolve. The 12th Amendment, ratified in 1804, separated the two elections and quietly demoted the office for a century and a half (Senate Historical Office, briefing on the Vice President). What the era left behind was procedural rather than political, and durable: Jefferson, presiding over a chamber he could not vote in, wrote his Manual of Parliamentary Practice, and the House of Representatives still incorporates it into its rules today.

Adams used his 29 tie-breaking votes to settle questions as large as whether a president may remove executive officers without the Senate's consent, a question that shaped the entire executive branch, and to influence the location of the national capital and relations with Great Britain (Senate Historical Office). The office's first two decades produced less power but more precedent than any since. Calhoun then pressed the presiding role to its limit, casting 31 tie-breaking votes and remaining the only vice president to serve under two presidents and then resign, walking out in December 1832 to take a Senate seat and prosecute the nullification doctrine he had authored (Time, 2023). Three of the four heaviest tie-vote records in history, Calhoun's 31, Adams's 29, and Jefferson's presiding legacy, come from the office's first fifty years, before anyone thought of it as a waiting room.

Succession is the office's hidden mandate

Nine vice presidents have become president mid-term: eight on deaths, one on a resignation (Senate Historical Office). The ranking credits the ones whose vice presidency itself shaped the transfer. John Tyler, 31 days into the job in 1841, insisted he was president outright rather than a caretaker, a claim with no settled constitutional answer at the time; his precedent held through eight later successions and was finally codified in the 25th Amendment (National Archives). Harry Truman's 82-day vice presidency mattered for the opposite reason: he was kept so far outside the war's inner circle that he learned of the atomic bomb program only as president, and the shock of that gap permanently changed how administrations brief the second office (Miller Center).

Theodore Roosevelt's 194-day vice presidency demonstrated the office's raw contingency; McKinley's assassination made a 42-year-old the youngest president in history and redirected the presidency toward the Progressive model (Miller Center). Lyndon Johnson executed the most scrutinized succession of the century after Kennedy's assassination in 1963. And Gerald Ford's case completed the constitutional circuit, proving the 25th Amendment's appointment machinery worked under maximum stress in 1973 and 1974, when Ford became the only person ever to hold both offices without being elected to either (National Archives). Six of the fifteen ranked here earn their place chiefly through succession, which is the office's oldest reason for existing and its least predictable.

The certification role and January 6

One power sat almost unnoticed in the office for two centuries before it became the most examined act any vice president has performed. Under the 12th Amendment and the Electoral Count Act, the vice president presides over the joint session that counts electoral votes. For most of American history this was ceremonial; several vice presidents, including Nixon in 1961, Gore in 2001, and Biden in 2017, presided over the certification of their own defeats without incident.

On January 6, 2021, Mike Pence presided over the electoral count and refused demands to reject or return certified slates of electors, the most consequential single exercise of the office's certification role in its history (Senate Historical Office). Pence ranks eleventh on a body of work that also includes 13 tie-breaking votes, the third most of any modern vice president, and the first tie-break ever cast to confirm a cabinet secretary, Betsy DeVos, on February 7, 2017 (NPR, 2017). Congress rewrote the Electoral Count Act in 2022 to state explicitly that the vice president's role in the count is ceremonial, converting a contested precedent into black-letter law. The certification power, dormant for 230 years, is now the most closely defined duty the office carries.

The modern office keeps setting records

The last decade has been the most active in the office's history by its own official metric. Pence cast 13 tie-breaking votes including the first ever to confirm a cabinet nominee. Harris then broke a 191-year-old record in under three years, and her 33 ties included the votes that carried the American Rescue Plan and the Inflation Reduction Act into law (NBC News, 2023; Senate Historical Office). The sitting vice president, JD Vance, reached 8 tie-breaking votes by early 2026, including passage of the 2025 budget reconciliation act in July 2025 and a January 14, 2026 vote that turned back a Venezuela war powers resolution (Senate Historical Office; PBS, 2025; CNBC, 2026). Vance is unranked here because grading an unfinished term against completed ones would be guessing.

The trend, however, is documented: narrow Senates have converted the vice presidency's sleepiest formal power into a routine instrument of lawmaking. The Senate reached its 300th recorded tie-break only in December 2023, and vice presidents have added several more since, so a meaningful share of all such votes in history were cast in the last five years (Senate Historical Office, Votes to Break Ties). Three of the last four vice presidencies rank among the most active vote-breaking terms ever recorded. An office designed as a waiting room now regularly decides what becomes law, even as the same decade turned its dormant certification power into the most litigated duty it holds. Only actions matter in this ranking, and the modern office is producing more countable actions than any era before it.
