Legislative branch

Created by Article I

U.S. Representative

435 voting members (+6 non-voting delegates)

The chamber closest to the people by design: the whole House answers to voters every two years, and revenue bills must start here.

Chosen: Elected directly by the voters of a congressional district, every district electing in every even-numbered year.
Term: 2 years
Limit: None States cannot impose congressional term limits (U.S. Term Limits v. Thornton, 1995); only a constitutional amendment could.
Qualifies: At least 25 years old, a U.S. citizen for 7 years, and an inhabitant of the state (not necessarily the district) when elected.
Removed: Expulsion by a two-thirds vote of the House. Members of Congress are not subject to impeachment.
Vacancy: Special election called by the state's governor. The House is never filled by appointment.

U.S. Senator

100 (2 per state)

The slower, smaller chamber: six-year terms, statewide constituencies, and the exclusive powers to confirm officials and try impeachments.

Chosen: Elected statewide to staggered six-year terms; one of the three Senate classes is up in each even-numbered year. Directly elected only since the Seventeenth Amendment (1913).
Term: 6 years
Limit: None As with the House, term limits would require a constitutional amendment.
Qualifies: At least 30 years old, a U.S. citizen for 9 years, and an inhabitant of the state when elected.
Removed: Expulsion by a two-thirds vote of the Senate. Not subject to impeachment.
Vacancy: In most states the governor appoints a temporary senator until a special or regular election, as the Seventeenth Amendment permits.

Speaker of the House

The House's presiding officer and, in practice, the majority party's chief strategist: the Speaker controls the floor agenda and is second in the presidential line of succession.

Chosen: Elected by the full House at the start of each Congress (and whenever the office falls vacant), which in practice means chosen by the majority party.
Term: 2 years (the life of a Congress)
Limit: None
Qualifies: The Constitution sets none, and does not even require the Speaker to be a House member, though every Speaker has been one.
Removed: The House can vacate the chair by majority vote (a 'motion to vacate') or simply elect someone else at any time.
Vacancy: The House elects a new Speaker; a Speaker pro tempore from a designated list presides in the interim.

President pro tempore of the Senate

The Senate's constitutional presiding officer when the Vice President is absent, third in the line of succession, and in modern practice a largely honorific post held by the majority's senior member.

Chosen: Elected by the Senate; by unbroken modern custom, the most senior senator of the majority party.
Term: Until the Senate chooses otherwise
Limit: None
Qualifies: Must be a sitting senator (the office presides 'in the Absence of the Vice President').
Removed: The Senate may elect a replacement at any time.
Vacancy: The Senate elects a successor, typically at the start of a Congress or on a change of majority.

Executive branch

Created by Article II

President of the United States

The whole executive power vested in one person: chief executive, commander in chief, chief diplomat, and the only official (with the VP) elected by the nation as a whole.

Chosen: Elected every four years through the Electoral College: state popular votes appoint 538 electors, and 270 electoral votes win the office.
Term: 4 years
Limit: Two elected terms The Twenty-Second Amendment (1951) caps a President at two elected terms, plus at most two years of a predecessor's term, after Franklin Roosevelt's four elections.
Qualifies: A natural-born citizen, at least 35 years old, and 14 years a resident of the United States.
Removed: Impeachment by the House and conviction by two-thirds of the Senate. The Twenty-Fifth Amendment separately covers inability, voluntary or declared.
Vacancy: The Vice President becomes President. Further down, the Presidential Succession Act orders the Speaker, the president pro tempore, then the Cabinet.

Vice President

Constitutionally a hybrid: first in line for the presidency, and president of the Senate with a vote only to break ties, everything else about the job is what the President delegates.

Chosen: Elected on the presidential ticket through the same Electoral College vote (electors cast separate ballots for President and Vice President under the Twelfth Amendment).
Term: 4 years
Limit: None as VP The Twenty-Second Amendment limits only the presidency; a two-term President could constitutionally serve later as VP, though the question has never been tested.
Qualifies: The same as the President's: natural-born citizen, 35, and 14 years a resident, since the VP must be eligible to succeed.
Removed: Impeachment and Senate conviction, like all civil officers.
Vacancy: The President nominates a new VP, confirmed by majority of both chambers (Twenty-Fifth Amendment), used for Ford (1973) and Rockefeller (1974).

Chosen: Nominated by the President and confirmed by a Senate majority. Serves at the President's pleasure.

Judicial branch

Created by Article III

Supreme Court Justice

9 (set by statute, not the Constitution)

Nine lifetime appointees with the last word on what federal law and the Constitution mean, which is why each vacancy becomes a national event.

Chosen: Nominated by the President and confirmed by a Senate majority.
Term: Life (during good behavior)
Limit: None Life tenure is the Constitution's design for judicial independence; any fixed term would require an amendment.
Qualifies: None whatsoever in the Constitution, no age, citizenship, or even law degree requirement.
Removed: Impeachment by the House and conviction by two-thirds of the Senate. One justice has been impeached (Samuel Chase, 1804); none has been removed.

The trial and appeals judges who decide nearly every federal case that will ever exist, the Supreme Court hears fewer than a hundred a year; these courts handle hundreds of thousands.

Chosen: Nominated by the President and confirmed by a Senate majority, district judges for the 94 districts, circuit judges for the 13 courts of appeals.
Term: Life (during good behavior)
Limit: None Judges may take 'senior status' at retirement eligibility, keeping a reduced caseload while opening their seat for a new appointment.

Removed: Impeachment and Senate conviction, the only way. Eight federal judges have been removed this way, the only officials ever removed by impeachment.
