EXPLANATORY FILE Six files of supplementary materials are available for the Perspectives on Politics article "Waking Up in the Poll Booth" by Robert E. Goodin and James Mahmud Rice. These files are: * Explanatory File * Opinion Poll Data for the UK * Opinion Poll Data for the US * Opinion Poll Data for Australia * SPSS Code for the British Election Campaign Study 1987 * SPSS Code for the British Election Study 2005 Rolling Campaign Panel Survey The explanatory file is this text file (Explanatory_File.txt), which describes these supplementary materials. The other files are explained below. OPINION POLL DATA FOR THE UK, THE US, AND AUSTRALIA A comma-delimited file (Opinion_UK.csv) contains the opinion poll data for the UK used to produce the pre-campaign and pre-election percentage shares of voting intentions reported in Table 1 of the article, with the exception of those for 2005. The data in this file comes from Gallup poll results reported in King, Wybrow, and Gallup 2001, 1-21. The 2005 pre-campaign and pre-election percentage shares of voting intentions in Table 1 are based on the British Election Study 2005 Rolling Campaign Panel Survey (see below), since Gallup polls were no longer being conducted in the UK by the time of the 2005 election. A comma-delimited file (Opinion_US.csv) contains the opinion poll data for the US used to produce the pre-campaign and pre-election approval ratings reported in Table 2. The data in this file comes from Gallup poll results reported in Roper Center for Public Opinion Research 2007. Similarly, a comma-delimited file (Opinion_Australia.csv) contains the opinion poll data for Australia used to produce the pre-campaign and pre-election percentage shares of voting intentions reported in Table 3. The data in this file comes from Morgan Gallup poll results reported in various issues of Morgan Gallup Poll Findings and in Roy Morgan Research 2008. These three files have the same structure. For each file, the first row contains the names of the variables included in the file. These are: COUNTRY, ELECTION_YEAR, ELECTION, PERIOD, START_YEAR, START_MONTH, START_DAY, END_YEAR, END_MONTH, END_DAY, PARTY_PRESIDENT, and OPINION. Each subsequent row relates to a particular, single opinion poll and contains that opinion poll's scores on these variables. The variables included in these three files have the following meanings. COUNTRY: the country in which the opinion poll was conducted (either the UK, the US, or Australia). ELECTION_YEAR: the year of the election anticipated by the opinion poll. ELECTION: whether the election anticipated by the opinion poll is the first or the second election to be held that year. PERIOD: whether the opinion poll was conducted during the pre-campaign or the pre-election period. START_YEAR, START_MONTH, and START_DAY: these variables describe the date fieldwork for the opinion poll started. END_YEAR, END_MONTH, and END_DAY: these variables describe the date fieldwork for the opinion poll ended. PARTY_PRESIDENT: the party (in the UK or Australia) or the president (in the US) which is the subject of the OPINION variable. OPINION: the percentage share of voting intentions (in the UK or Australia) or the approval rating (in the US) reported by the opinion poll. SPSS CODE FOR THE BRITISH ELECTION CAMPAIGN STUDY 1987 A text file (SPSS_BECS_1987.txt) contains the SPSS code used to analyze the British Election Campaign Study 1987. This analysis produced the 1987 results reported in Table 4 of the article. This analysis also produced exploratory estimates of percentage shares of pre-campaign voting intentions, pre-election voting intentions, and the popular vote in 1987, based on the British Election Campaign Study 1987. These exploratory estimates are akin to figures reported in Table 1 of the article, although the figures in Table 1 are based on Gallup polls and official election returns. For more information about the British Election Campaign Study 1987, see Miller 1989 and Miller et al. 1990. SPSS CODE FOR THE BRITISH ELECTION STUDY 2005 ROLLING CAMPAIGN PANEL SURVEY A text file (SPSS_BES_2005_RCPS.txt) contains the SPSS code used to analyze the British Election Study 2005 Rolling Campaign Panel Survey. This analysis produced the 2005 estimates of percentage shares of pre-campaign and pre-election voting intentions reported in Table 1 of the article. This analysis also produced the 2005 results reported in Table 4. For more information about the British Election Study 2005 Rolling Campaign Panel Survey, see British Election Study 2005.
