Summary note
This poll, fielded April 9-11, 2007, is a part of a continuing series of monthly surveys that solicit public opinion on the presidency and on a range of other political and social issues. Respondents were asked whether they approved of the way President George W. Bush was handling his presidency and foreign policy, and were asked to rate the condition of the national economy, to identify the most important problem facing the country, and to say whether they approved of the way the United States Congress was handling its job. Respondents were asked to give their opinions of Speaker of the House Nancy Pelosi and the potential 2008 presidential candidates, whether respondents had been paying attention to the 2008 presidential campaign, whether they were satisfied with the Democratic and Republican candidates running for nomination for president, and whether respondents were likely to vote in the Democratic or Republican presidential primary. Opinions were gathered about who respondents expected to win the Democratic and Republican nominations for president in 2008, Al Gore's position on the environment, and whether the Republican party's principles related to that of former President Ronald Reagan. Several questions were asked about the war in Iraq, including whether the United States did the right thing in taking military action against Iraq, whether the United States was right to remove Saddam Hussein, whether Congress should block funding for the war, and whether the United States should withdraw its troops from Iraq. Additional topics include Alberto Gonzales and the firings of United States attorneys by the Department of Justice, whether respondents had filed their income taxes, respondents' financial concerns, political campaign advertising on television, and the re-occurrence of Elizabeth Edwards' cancer and how it may affect presidential candidate John Edwards. Demographic information includes sex, age, race, education level, household income, marital status, religious preference, frequency of religious attendance, type of residential area (e.g., urban or rural), political party affiliation, political philosophy,voter registration status and participation history, perceived social class, the presence of children under 18 and household members between the ages of 18 and 24, and whether respondents had any children planning to attend a four-year college.

Case file characteristics
Weight: the data contain weight variables that should be used in analyzing the data. According the CBS News Web site, data were weighted to match United States Census Bureau breakdowns on age, sex, race, education, and region of the country. The data were also adjusted for the fact that people who share a phone with others have less chance to be contacted than people who live alone and have their own phones, and that households with more than one telephone number have more chances to be called than households with only one phone number.
Methodology note
  • Mode of data collection: telephone interview.
  • Sample: a variation of random-digit dialing using primary sampling units (PSUs) was employed, consisting of blocks of 100 telephone numbers identical through the eighth digit and stratified by geographic region, area code, and size of place. Within households, respondents were selected using a method developed by Leslie Kish and modified by Charles Backstrom and Gerald Hursh (see Backstrom and Hursh, SURVEY RESEARCH. Evanston, IL: Northwestern University Press, 1963).
  • Universe: persons aged 18 and over living in households with telephones in the contiguous 48 United States.
