Chapter 6: The Politics of Public Opinion
6.1 The Nature of Public Opinion (Link to 6.1)
Public opinion is more than a collection of answers to a question on a poll; it represents a snapshot of how people’s experiences and beliefs have led them to feel about a candidate, a law, or a social issue. Our attitudes are formed in childhood as part of our upbringing. They blend with our closely held beliefs about life and politics to form the basis for our opinions. Beginning early in life, we learn about politics from agents of socialization, which include family, schools, friends, religious organizations, and the media. Socialization gives us the information necessary to understand our political system and make decisions. We use this information to choose our ideology and decide what the proper role of government should be in our society.

6.2 How Is Public Opinion Measured? (Link to 6.2)
The purpose of a poll is to identify how a population feels about an issue or candidate. Many polling companies and news outlets use statisticians and social scientists to design accurate and scientific polls and to reduce errors. A scientific poll will try to create a representative and random sample to ensure the responses are similar to what the actual population of an area believes. Scientific polls also have lower margins of error, which means they better predict what the overall public or population thinks. Most polls are administered through phones, online, or via social media. Even in scientific polls, issues like timing, social pressure, lack of knowledge, and human nature can create results that do not match true public opinion. Polls can also be used as campaign devices to try to change a voter’s mind on an issue or candidate.

6.3 What Does the Public Think? (Link to 6.3)
When citizens change their sources of information, their opinions may change. The influence of elites and workplaces, life experiences, and state political culture can all help change our opinions. Economic and social policies are likely to cause controversy if the government has to serve the needs of many different groups or balance rights and liberties, all with limited resources.
What Americans think about their government institutions shifts over time as well. Overall approval for presidents begins high and drops over time, with expected increases and decreases occurring due to domestic and international events. Approval for Congress changes more dramatically with domestic events and partisan behavior. The public has a lower opinion of Congress than of the president, and recent congressional approval levels have hovered between 10 and 20 percent. The Supreme Court has the most stable public approval ratings, possibly due to its less visible nature. But the court’s ratings can be affected by controversial decisions, such as its 2015 decisions on the Affordable Care Act and same-sex marriage.

6.4 The Effects of Public Opinion (Link to 6.4)
Public opinion polls have some effect on politics, most strongly during election season. Candidates who do well in polls receive more media coverage and campaign donations than candidates who fare poorly. The effect of polling on government institutions is less clear. Presidents sometimes consider polls when making decisions, especially if the polls reflect high approval. A president who has an electoral mandate can use that high public approval rating to push policies through Congress. Congress is likely to be aware of public opinion on issues. Representatives must continually raise campaign donations for bi-yearly elections. For this reason, they must keep their constituents and donors happy. Representatives are also likely to change their voting behavior if public opinion changes. Senators have a longer span between elections, which gives them time to make decisions independent of opinion and then make amends with their constituents. Changes in public opinion do not affect senators’ votes, but they do cause senators to lose reelection. It is less clear whether Supreme Court justices rule in ways that maintain the integrity of the branch or that keep step with the majority opinion of the public, but public approval of the court can change after high-profile decisions.
Why would House of Representative members be more likely than the president to follow public opinion?
