Equality of opportunity

The idea that everyone should have the same chance to succeed under the law and in society, even if outcomes end up unequal.

Free enterprise / Free market (laissez-faire)

An economic system where businesses and individuals make economic decisions with minimal government interference. Laissez-faire is French for "let it be."

Rule of law

Political socialization

The process by which people develop their political beliefs and values through influences like family, school, peers, media, religion, and community.

Political ideology

A consistent set of beliefs about the role of government and how society and the economy should work. It shapes how people vote and which policies they support.

Effects of globalization

Globalization is the growing worldwide connection of economies, cultures, and politics. Effects include more trade and cheaper goods, job outsourcing and lost manufacturing jobs, faster spread of ideas, and debates over trade policy and immigration.

Generational effects

Political views shaped by the major events and conditions a generation lived through while growing up, which tend to stay with that group.

Life-cycle effects

Changes in political views and behavior that come from a person's age or stage of life, rather than from the era they grew up in.

Scientific polls

Polls that use a representative, randomly selected sample and careful methods so results can be generalized to the whole population within a margin of error.

Public opinion polls

Surveys that measure what people think about political leaders, issues, and policies. Used by candidates, parties, the media, and officials to track the public mood.

Polling methodology

The methods used to design and conduct a poll: who is sampled, how people are contacted, how questions are worded, sample size, and how results are analyzed. Good methodology makes a poll reliable and valid.

Sampling techniques

The ways pollsters choose a small group to represent a larger population (random, stratified, etc.). A larger, well-chosen sample gives more accurate results.

Random sampling

A technique where every member of the population has an equal chance of being selected. This reduces bias and makes the sample representative.

Sampling error

The difference between a sample's results and the true population's views, usually reported as the margin of error (e.g., +/- 3%). Larger samples reduce it.

Question wording (neutral / biased)

How a question is phrased can change the answer. Neutral wording is balanced and unbiased. Biased (loaded) wording pushes respondents toward a particular answer and makes the results unreliable.

Entrance and exit polls

Entrance polls survey voters as they arrive at the polls; exit polls survey voters right after they vote. Used to learn who voted for whom and why, and to help media project results.

Benchmark / tracking polls

Benchmark polls are the first poll a campaign takes to measure a candidate's starting support and name recognition. Tracking polls are repeated polls over time to see how opinion changes, especially close to an election.

Focus groups

Small groups of people guided through a discussion to give in-depth opinions about candidates, messages, or ads. They give detailed, qualitative feedback but are not statistically representative.

Liberal ideologies

Generally favor an active role for the federal government in the economy and in promoting equality and social welfare, higher taxes on the wealthy, regulation of business, and more social-issue freedom. Associated more with the Democratic Party.

Conservative ideologies

Generally favor limited government, lower taxes, fewer regulations, free markets, a strong national defense, and traditional social values. Associated more with the Republican Party.

Moderate

A person who holds a mix of liberal and conservative views, or stays near the center of the ideological spectrum. Moderates are often swing voters.

Populist

A person or movement that claims to represent "ordinary people" against elites and established institutions. Populism can appear on the left or the right.

Green Party

A third party focused on environmental protection, social justice, grassroots democracy, and nonviolence. Leans left on most issues.

Wedge issues and valence issues

Wedge issues are controversial issues that split a party or group and can pull voters away (e.g., abortion, immigration). Valence issues are issues almost everyone agrees on, so candidates compete on who can handle them best (e.g., a strong economy, safe communities).

Party platforms

A formal statement of a party's goals, beliefs, and policy positions, adopted at the national party convention every four years. Platforms guide candidates but do not legally bind them.

Public policy / Policy

Fiscal policy

Government's use of taxing and spending to influence the economy. Set by Congress and the president through the budget. Ex: A tax cut or stimulus spending.

Mandatory spending

Federal spending required by existing law, so Congress does not vote on it each year. About two-thirds of the budget. Ex: Social Security, Medicare, Medicaid.

Federal spending that Congress decides on each year through appropriations. Ex: Defense, education, transportation, scientific research.

Entitlements

Government benefits that people automatically qualify for if they meet certain legal requirements, such as age or income. Ex: Social Security and Medicare.

Social Security

A federal program funded by payroll taxes that provides monthly income to retirees, people with disabilities, and survivors. The largest entitlement program.

Tax revenue / Income taxes

Tax revenue is the money government collects from taxes to fund its programs. Income taxes are taxes on earnings and are the largest source of federal revenue. Authorized by the 16th Amendment.

Progressive / Regressive / Flat tax

Progressive tax: higher earners pay a higher percentage (the U.S. federal income tax). Regressive tax: takes a larger percentage from lower earners (e.g., sales tax). Flat tax: everyone pays the same percentage.

Federal Reserve (Fed)

The nation's central bank. It controls monetary policy by adjusting interest rates and the money supply to keep prices stable and employment high. Run by a Board of Governors and independent from day-to-day politics.

Budget deficit

National debt

The total amount of money the federal government owes, built up from all past deficits (minus surpluses). Deficit = one year; debt = the total.

Debt ceiling

A legal limit set by Congress on how much the federal government can borrow. Raising it lets the government pay bills it has already committed to; failing to raise it risks default.

Keynesianism

Economic theory (John Maynard Keynes) that government should increase spending or cut taxes during recessions to boost demand and create jobs, and cut back in good times. Demand-side approach favored by liberals.

Supply-side economics

Theory that lower taxes and less regulation, especially for businesses and high earners, encourage investment, production, and job growth that will benefit the whole economy. Often called trickle-down economics; favored by conservatives.

Inflation

A general, sustained rise in prices over time, which reduces the purchasing power of money. The Fed raises interest rates to help slow it.

Employment / Unemployment rate

The unemployment rate is the percentage of people in the labor force who are actively looking for work but do not have a job. Low unemployment signals a strong economy; high unemployment signals a weak one.

16th Amendment (1913)

Gives Congress the power to levy a federal income tax without dividing it among the states by population. It overturned earlier Supreme Court limits and made income tax the main source of federal revenue.
