This poll 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 special topic poll, fielded January 5-6, 2008, surveyed New Hampshire registered voters first interviewed November 9-12, 2007, to measure the amount of individual change. The dataset includes the responses to call-back questions as well as to questions in the original poll, CBS NEWS/NEW YORK TIMES NEW HAMPSHIRE PRIMARY POLL, NOVEMBER 2007 (ICPSR 24362), which queried New Hampshire residents on George W. Bush's presidency, the 2008 presidential race, whether respondents were going to vote in the Democratic or Republican primary and for whom, which issues were most important to them, and whether they had attended the New Hampshire Democratic Caucus in 2004. Additional topics included abortion, illegal immigration, whether Iran was a threat to the United States, the cost of living in New Hampshire, the war in Iraq, and gun ownership. In the call-back poll conducted a few days prior to the New Hampshire primary held January 8, 2008, registered voters were re-interviewed about how much attention they were paying to the 2008 presidential race, the likelihood that they would vote in the New Hampshire primary on the following Tuesday and for whom, whether they had recommended their candidate to anyone, which party they usually voted for in national and statewide elections, the importance of the results of the Iowa caucus in their vote, and their opinions of the candidates. Demographic information includes sex, age, race, education level, household income, marital status, religious preference, frequency of religious attendance, labor union membership, type of residential area (e.g., urban or rural), political party affiliation, political philosophy, voter registration status and participation history, and the presence of children in the household under the age of 18.

This call-back poll re-interviewed 619 registered voters who had participated in the CBS NEWS/NEW YORK TIMES NEW HAMPSHIRE PRIMARY POLL, NOVEMBER 2007 (ICPSR 24362). This data collection includes their responses to questions from the original poll as well as to the call-back questions. Original survey questions are identified with the prefix "Q", while call-back questions are identified as "RQ".

The CASEID variable was reformatted in order to make it a unique identifier.

Value labels for unknown codes were added in variables Q21, RQ11, and RQ21.

This data collection was produced by CBS News, New York, NY.

Only registered voters from the original survey (November 9-12, 2007) were re-interviewed in the January 2008 call-back poll. In the original November 2007 survey, 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).

Persons aged 18 and over living in households with telephones in the state of New Hampshire.

2009-08-31 ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major statistical software formats as well as standard codebooks to accompany the data. In addition to these procedures, ICPSR performed the following processing steps for this data collection:

  • Created variable labels and/or value labels.
  • Created online analysis version with question text.
  • Checked for undocumented or out-of-range codes.

The data contain weight variables that should be used in analyzing the data. The call-back registered voter weight (variable WGHT) was based on the population weight from the original November 2007 survey, post-stratified to the November poll registered voter distributions on: age, sex, likelihood of voting (definitely, probably, and not/DK), education level (high school or less, some college, bachelors, or post-graduate), and original November candidate choice (McCain, Romney, Giuliani, Huckabee, other Republican candidate, Clinton, Edwards, Obama, or other Democratic candidate). The likely voter weight variables (WGT2 and WGT3) for the November 2007 and January 2008 polls were based on the population weight (WGHT), with adjustments for respondent-reported propensity to vote (variable RQ1 in the call-back poll), respondent-reported attention to the campaign (RQ5 in the call-back poll), respondent-reported decision about which party's primary to vote in (RQ2 in the call-back poll), and respondent-reported past primary participation (Q7 from the original survey).
