Find three different public opinion polls (from different sources) on the same current political issue (for example, the national debt, Social Security, health care reform, climate change, etc). Discuss the findings of these various polls. Are the results of the three polls similar or different? Why do you think that might be the case? How might the sample, sample size, type of poll, time period in which the poll was conducted, or wording of the questions have affected the results? Are there any other elements that may have affected the results of the polls?
