Summary

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.
