6.4 The effects of public opinion  (Page 4/23)

The short answer is “sometimes.” The public is not perfectly informed about politics, so politicians realize public opinion may not always be the right choice. Yet many political studies, from the American Voter in the 1920s to the American Voter Revisited in the 2000s, have found that voters behave rationally despite having limited information. Individual citizens do not take the time to become fully informed about all aspects of politics, yet their collective behavior and the opinions they hold as a group make sense. They appear to be informed just enough, using preferences like their political ideology and party membership, to make decisions and hold politicians accountable during an election year.

Overall, the collective public opinion of a country changes over time, even if party membership or ideology does not change dramatically. As James Stimson’s prominent study found, the public’s mood, or collective opinion, can become more or less liberal from decade to decade. While the initial study on public mood revealed that the economy has a profound effect on American opinion,

Individually, of course, politicians cannot predict what will happen in the future or who will oppose them in the next few elections. They can look to see where the public is in agreement as a body. If public mood changes, the politicians may change positions to match the public mood. The more savvy politicians look carefully to recognize when shifts occur. When the public is more or less liberal, the politicians may make slight adjustments to their behavior to match. Politicians who frequently seek to win office, like House members, will pay attention to the long- and short-term changes in opinion. By doing this, they will be less likely to lose on Election Day.

Public opinion of the president is different from public opinion of Congress. Congress is an institution of 535 members, and opinion polls look at both the institution and its individual members. The president is both a person and the head of an institution. The media pays close attention to any president’s actions, and the public is generally well informed and aware of the office and its current occupant. Perhaps this is why public opinion has an inconsistent effect on presidents’ decisions. As early as Franklin D. Roosevelt ’s administration in the 1930s, presidents have regularly polled the public, and since Richard Nixon ’s term (1969–1974), they have admitted to using polling as part of the decision-making process.
