Political Beliefs and Behavior
Socialization and ideology
Family is the strongest early agent of political socialization; schools, peers, religion, and media reinforce or modify it. Most Americans cluster near the ideological middle. In U.S. usage, "liberal" generally means favoring government action on economic and social problems; "conservative" favors markets, tradition, and decentralized government. Libertarians and populists combine these dimensions differently, so an issue position alone will not reveal a label.
Measuring opinion
Valid polls rest on random sampling. Sampling error shrinks with sample size - roughly plus or minus three points for 1,000 respondents - but a huge sample does not correct a biased one (the Literary Digest's 1936 failure). Watch for question wording, push polls, nonresponse bias, and exit polls' sampling limits.
Participation
Voting is the most common participatory act, yet U.S. turnout trails other democracies, largely because of registration requirements, frequent elections, and the two-party framework. Education, age, and income predict turnout; rational-choice models weigh the costs of voting against the marginal benefit.
Voting behavior
Party identification dominates; retrospective voting rewards or punishes the incumbent's record; prospective voting weighs promises and issue positions; candidate image matters most for low-information voters.
Media
Agenda setting determines what people think about; framing shapes how they think about it; horse-race coverage emphasizes strategy over substance. The equal time rule applies to broadcast licensing.
Rule of thumb
For any polling question, first ask who was sampled and how they were selected - representativeness, not size, makes a poll trustworthy.
