Political glossary

The jargon of politics is a barrier by design. Here are the terms you’ll run into most, in plain English — neutral definitions anyone can use.

A

Absentee / mail ballot

A ballot voted and returned by mail (or a drop box) instead of in person. Rules vary by state; some states mail a ballot to every voter, others require a request or an excuse.

Amendment

A formal change to a bill or to the Constitution. Constitutional amendments require a two-thirds vote of Congress (or a convention) and ratification by three-quarters of the states.

Appropriations

The laws that actually fund the government by setting how much each agency and program can spend. Failure to pass them on time can lead to a government shutdown.

B

Ballot initiative

A law or amendment placed directly on the ballot by citizens who gather enough signatures, letting voters decide it themselves rather than the legislature.

Ballot measure

Any question voters decide directly on a ballot — including citizen initiatives and referendums placed there by a legislature.

Bicameral

A legislature with two chambers. Congress is bicameral: the House of Representatives and the Senate. Most state legislatures are bicameral too (Nebraska is the exception).

Bill

A proposed law. A bill becomes law only after passing both chambers of a legislature in identical form and being signed by the executive (or having a veto overridden).

Bipartisan

Supported by members of both major parties. A bipartisan bill has backing from both Democrats and Republicans.

C

Caucus

Two meanings: (1) a meeting where party members gather to choose candidates or delegates, used instead of a primary in some states; (2) a group of lawmakers organized around a shared interest, like the Congressional Black Caucus.

Checks and balances

The way the three branches of government — legislative, executive, and judicial — each limit the power of the others, so no single branch can dominate.

Cloture

A Senate procedure to end debate on a measure and force a vote. It usually takes 60 votes, which is why many bills effectively need a 60-vote supermajority to advance.

Constituent

A person an elected official represents. When you call your member of Congress as someone who lives in their district or state, you're a constituent — which is why your voice carries weight.

Continuing resolution

A stopgap law that keeps the government funded at existing levels when Congress hasn't passed full appropriations on time — a way to avoid or end a shutdown.

Convention

A party gathering where delegates formally nominate candidates and adopt the platform. The national conventions are held every four years ahead of the presidential election.

D

Debt ceiling

A legal cap on how much the federal government can borrow to pay obligations it has already incurred. Raising it doesn't authorize new spending; it lets the Treasury pay bills Congress already approved.

Deficit vs. debt

The deficit is how much more the government spends than it takes in during a single year. The national debt is the running total of all past deficits, minus surpluses.

Delegate / superdelegate

Delegates represent voters at a party convention and are mostly awarded based on primary and caucus results. Superdelegates (party leaders and elected officials) can support any candidate; in the modern Democratic process their influence on the first nominating ballot is limited.

Down-ballot

Races that appear below the top of the ticket — Congress, state legislature, judges, school board — which often decide the most about daily life but get the least attention.

Due process

The constitutional guarantee that the government must follow fair procedures and respect your legal rights before depriving you of life, liberty, or property.

E

Early voting

Casting your ballot in person before Election Day during a designated period. Availability and dates vary by state.

Earmark

A provision directing federal funds to a specific project or locality, often added by an individual lawmaker. Sometimes called pork-barrel spending.

Electoral College

The system that formally elects the president. Each state gets electors equal to its members of Congress; a candidate needs 270 of 538 to win. Most states award all their electors to the statewide winner.

Entitlement program

A program that pays benefits to everyone who meets set eligibility rules, such as Social Security, Medicare, and Medicaid. Spending is driven by how many people qualify, not by an annual budget vote.

Executive order

A directive from the president (or a governor) managing the operations of the executive branch. It carries the force of law but cannot override statutes and can be reversed by a future executive or struck down by courts.

Executive privilege

A president's claimed right to keep certain communications confidential from Congress or the courts. It is not absolute and can be overridden, especially in criminal matters.

F

Federalism

The division of power between the national government and the states. It's why voting rules, schools, and many laws differ from one state to the next.

Filibuster

A tactic to delay or block a Senate vote by extending debate. Overcoming it requires cloture (usually 60 votes), giving the minority significant leverage.

Filibuster-proof majority

Control of at least 60 Senate seats — enough to end a filibuster without any votes from the other party. Rare in modern times.

Fiscal year

The 12-month period a government uses for budgeting. The U.S. federal fiscal year runs from October 1 to September 30.

G

Gerrymandering

Drawing district lines to favor one party or group. Independent redistricting commissions are one reform meant to reduce it.

Grassroots

Political activity driven by ordinary people at the local level — volunteers, small donors, neighborhood organizing — rather than by party leaders or big money.

H

Habeas corpus

A legal action requiring that a person who is detained be brought before a court, so a judge can decide whether the detention is lawful — a core protection against unlawful imprisonment.

I

Impeachment

The constitutional process for charging a federal official with misconduct. The House impeaches (formally accuses) by majority vote; the Senate then holds a trial, and conviction and removal require a two-thirds vote.

Incumbent

The person currently holding an office. Incumbents usually enjoy advantages in name recognition, fundraising, and constituent services.

J

Judicial review

The power of courts to decide whether laws and government actions are constitutional, and to strike down those that are not. Established in the U.S. by Marbury v. Madison (1803).

L

Lame duck

An official still in office after their successor has been elected but before the handover. A 'lame-duck session' is when a legislature meets during that window.

Line of succession

The order in which officials take over the presidency if it becomes vacant: the vice president first, then the Speaker of the House, then the president pro tempore of the Senate, then Cabinet secretaries.

Lobbying

Trying to influence legislation or policy, typically by professional advocates for an interest group. Federal lobbyists must register and disclose their activity.

M

Majority / minority leader

The elected heads of each party within a legislative chamber. The majority leader sets the agenda; the minority leader leads the opposition party.

Mandate

The claim that an election victory gives the winner authority to carry out their agenda. How strong a 'mandate' is depends on the margin and turnout — and is often contested.

Marginal tax rate

The tax rate applied to your next dollar of income, not to all of it. Because the U.S. uses brackets, moving into a higher bracket only taxes the income above that threshold at the higher rate.

Midterms

The federal elections held halfway through a president's term. All 435 House seats, about a third of the Senate, and many governorships and state offices are on the ballot.

P

PAC / Super PAC

A political action committee raises and spends money on elections. A traditional PAC gives limited amounts directly to candidates; a Super PAC can raise and spend unlimited sums independently but cannot coordinate with a campaign.

Platform

A party's official statement of its positions and goals, adopted at its national convention. Individual positions in it are called planks.

Precinct

The smallest election unit — the local area assigned to a single polling place. Precinct-level organizing is the building block of a campaign's ground game.

Primary

An election that narrows a party's field to a single nominee. In a closed primary only registered party members can vote; in an open primary any voter can participate.

Provisional ballot

A ballot cast when there's a question about a voter's eligibility. It's counted once election officials confirm the voter was eligible. You have the right to one in every state.

Q

Quorum

The minimum number of members who must be present for a legislature to conduct official business.

R

Ranked-choice voting

A system where voters rank candidates in order of preference. If no one wins a majority, the lowest finisher is eliminated and their votes redistributed until someone passes 50%.

Recall election

A vote to remove an elected official before their term ends. Available in some states and localities, usually requiring a petition to trigger it.

Reconciliation

A special budget process that lets certain tax and spending bills pass the Senate with a simple majority, bypassing the filibuster. Its use is limited to budget-related provisions.

Redistricting

Redrawing legislative district boundaries, normally every ten years after the census, to reflect population changes. Who controls the process can heavily shape election outcomes.

Referendum

A measure a legislature refers to voters for approval — for example, to ratify a law or a constitutional amendment. Unlike an initiative, it originates with the government, not citizens.

Roll-call vote

A recorded vote in which each legislator's yes or no is logged individually — creating the public record you can look up on Congress.gov or GovTrack.

S

Speaker of the House

The presiding officer of the U.S. House, elected by its members and typically the leader of the majority party. The Speaker is second in line to the presidency.

Supermajority

A threshold higher than a simple majority — commonly two-thirds or three-fifths — required for actions like overriding a veto, ending a filibuster, or amending the Constitution.

Swing / battleground state

A state where the two parties are competitive enough that either could win, making it decisive in national elections and a focus of campaign spending.

T

Term limits

Legal caps on how many terms someone can serve in an office. The presidency is limited to two terms; Congress has no term limits, though many states limit their own legislators and governors.

Turnout

The share of eligible voters who actually cast ballots. Because many races are decided by who shows up, turnout is often more decisive than persuasion.

V

Veto / override

A veto is the executive's rejection of a bill passed by the legislature. Legislators can override it — enacting the bill anyway — usually with a two-thirds vote of both chambers.

Voter ID

Laws about what identification, if any, a voter must show to cast a ballot. Requirements range from none to strict photo ID, and they vary widely by state.

Voter suppression

Tactics — legal or illegal — that make it harder for eligible people to register or vote, such as purges, reduced polling places, or misinformation about how and when to vote.

W

Whip

A party leader responsible for counting votes and rallying members to support the party's position on key legislation.

Writ of certiorari

An order by which the Supreme Court agrees to hear a case. The Court grants 'cert' to only a small fraction of the petitions it receives each year.
