title: CBS News Monthly Poll, March 2007
title: Version 1

description: This poll, fielded March 26-27, 2007, is a part of a continuing series
of monthly surveys that solicits public opinion on the presidency and on
a range of other political and social issues. This poll oversampled people who were likely to vote in the Democratic presidential primaries. All respondents were asked to say whether they approved of the way George W. Bush was
handling his job as president, whether they had been paying attention to the 2008 presidential campaign, to give their opinions of potential 2008 presidential candidates, and who they would most like to see nominated in the race for the Democratic party's presidential nomination. Opinions were solicited on Elizabeth Edwards, the wife of Democratic presidential candidate John Edwards,
and whether respondents had been paying attention to the news about her cancer reoccurrence, as well as whether John Edwards' presidential campaign would be affected by his wife's medical condition. Additional topics include breast cancer, firings of United States attorneys by the Justice Department
and Attorney General Alberto Gonzales, withdrawing the troops from Iraq, and whether Iran was a threat to the United States. Demographic information includes sex, age, race, education level, marital status, frequency of religious attendance, type of residential area (e.g., urban or rural), political party affiliation, political philosophy, voter registration status, and the presence of children under 18 and household members between the ages of 18 and 24.
description: 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. An oversample of registered voters who planned to vote in a Democratic primary in 2008
was also conducted for this poll. The subsample of all Democratic primary voters was weighted to the proportion of these voters across three previous 2007 CBS News
and CBS News/New York Times Polls.
description: 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). An oversample of registered voters who planned to vote in a Democratic primary in 2008 was also conducted for this poll, for a total of 539 interviews among this group.
