computer-assisted telephone interview (CATI) ICPSR created a unique sequential record identifier variable named CASEID for use with online analysis. The data available for download are not weighted and users will need to weight the data prior to analysis. Several codes in the variable CBSA contain diacritical marks. System missing values were recoded to -1. Variables FIPS and ZIP were recoded to protect respondent confidentiality. The variables PCTBLACK, PCTASIAN, PCTHISP, CONGDIST, BLOCKCNT, MSAFLAG, CSA, CBSA, METRODIV, ZIP, and NIELSMKT were converted from character to numeric. Variables MSA, CSA, CBSA, and METRODIV contain unknown codes. The data collection was produced by Taylor Nelson Sofres of Horsham, PA. Original reports using these data may be found via the ABC News Polling Unit Web site and via the Washington Post Opinion Surveys and Polls Web site.

ICPSR为计算机辅助电话调查（computer-assisted telephone interview, CATI）创建了一款名为CASEID的唯一序列记录标识符变量，以供在线分析使用。可供下载的原始数据未经过加权处理，使用者需在开展分析前自行对数据进行加权。变量CBSA中的部分编码带有变音符号。系统缺失值已被重编码为-1。为保护受访者隐私，FIPS与ZIP变量已完成重编码。PCTBLACK、PCTASIAN、PCTHISP、CONGDIST、BLOCKCNT、MSAFLAG、CSA、CBSA、METRODIV、ZIP及NIELSMKT等变量已从字符型转换为数值型。MSA、CSA、CBSA及METRODIV变量包含未知编码。本数据集的采集工作由位于宾夕法尼亚州霍舍姆的泰勒纳尔逊索夫雷斯公司（Taylor Nelson Sofres）完成。依托本数据集撰写的原始报告可通过ABC新闻民意调查部门官网以及《华盛顿邮报》民意调查与舆情调研官网获取。
