title: Archival Version

description: This poll, fielded November 02-11, 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. All of the respondents to this poll were registered voters from Iowa. Respondents were asked whether they approved of the way George W. Bush was handling his job as president, whether George W. Bush's presidency had been a success, and whether they wanted to see a continuation of Bush's policies. Several questions pertaining to the 2008 presidential campaign were asked including how much attention respondents paid to the campaign, whether they attended any campaign events, whether respondents planned on attending the Iowa presidential caucus, and if so, whether they planned on attending the Democratic party caucus or the Republican party caucus. Respondents were asked their opinions of presidential candidates Hillary Clinton, John Edwards, Barack Obama, Bill Richardson, Joe Biden, Mike Gravel, Dennis Kucinich, John McCain, Mitt Romney, Rudy Giuliani, Fred Thompson, Mike Huckabee, Duncan Hunter, Ron Paul, and Tom Tancredo. Respondents were asked several questions about the presidential candidates including who they supported, why they supported that specific candidate, which candidate they thought was interesting, which candidate they thought had the best chance of winning, whether they thought each candidate shared the same values of most people in Iowa, whether each candidate said what they believed in, and whether the candidates talked enough about important issues facing the country. Information was also collected on the presence of firearms in the respondent's home and whether the respondent considered him or herself to be a born-again Christian. Additional topics that were addressed in this poll included illegal immigration, Social Security, United States involvement in Iraq, terrorism, and abortion. 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, the presence of children under 18, and labor union member status.
description: The data contain weight variables that should be used in analyzing the data. According to the CBS News Web site, data were weighted by probabilities of selection and by demographic characteristics to reflect the Iowa registered voter list. To create the probable electorates for each state, registered voters were also weighted by their intention of voting, their attention to the campaign, and factors related to their past voting behavior. Likely caucus-goers in Iowa represent 17 percent of the registered voter population.

The sample was drawn from three sources as indicated in the OSMP variable: the state of Iowa's registered voter list (matched to phone numbers where possible), an RDD phone sample with numbers that matched numbers on the registered voter list eliminated (in order to sample phone numbers unavailable on the state list), and a small cell phone sample.

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). The sample was drawn from three sources as indicated in the OSMP variable: the state of Iowa's registered voter list (matched to phone numbers where possible), an RDD phone sample with numbers that matched numbers on the registered voter list eliminated (in order to sample phone numbers unavailable on the state list), and a small cell phone sample.
