1. 1Preparação da base de dados
   ds_0004— | Variable Name | Description | | --- | --- | | congress | Two-year session of the U.S. Congress (numeric, 97–113 corresponding to 1981–2014). | | icpsr | Stable numeric identifier for the legislator/candidate from the ICPSR member/candidate coding scheme; constant across Congresses. | | party_code | Party identifier using standard ICPSR party codes (e.g., 100 = Democrat, 200 = Republican). | | nominate_dim1 | DW-NOMINATE first-dimension roll-call ideology score, scaled roughly liberal (negative) to conservative (positive) across all Congresses. | | nokken_poole_dim1 | Nokken–Poole first-dimension roll-call ideology score estimated separately within each Congress, allowing movement over time; liberal (negative) to conservative (positive). | | prog | Indicator for affiliation with the Congressional Progressive Caucus in that Congress (1 = member, 0 = not a member; may be blank before the caucus existed or if unknown). | | pop | Indicator for affiliation with the Populist Caucus in that Congress (1/0; may be blank when not applicable). | | new | Indicator for affiliation with the New Democrat Coalition in that Congress (1/0; may be blank when not applicable). | | bdc | Indicator for affiliation with the Blue Dog Coalition in that Congress (1/0; may be blank when not applicable). | | rmsp | Indicator for affiliation with the Republican Main Street Partnership in that Congress (1/0; may be blank when not applicable). | | rsc | Indicator for affiliation with the Republican Study Committee in that Congress (1/0; may be blank when not applicable). | | tea | Indicator for affiliation with the Tea Party Caucus in that Congress (1/0; may be blank when not applicable). | | lib | Indicator for affiliation with the House Liberty Caucus in that Congress (1/0; may be blank when not applicable). | | post109 | Convenience flag for Congresses at or after the 109th (1 for 2005–2006 and later; 0 otherwise). | | general_percent | Candidate’s vote share in the most recent U.S. House general election in percent (0–100). | | median_donor_current | Median contributor ideology (CF-score) among all donors to the candidate in the current two-year period; negative values indicate more liberal donor pools and positive values more conservative donor pools. | | mean_donor_current | Mean contributor ideology (CF-score) among all donors to the candidate in the current two-year period; same left–right orientation as the median. | | districtpres | District-level vote share for the Democratic presidential nominee in the most recent presidential election, in percent (0–100). | | primary_percent | Candidate’s vote share in the most recent U.S. House primary election in percent (0–100). | | bdc_incumbonly | Incumbent-only Blue Dog Coalition indicator in that Congress (1 if the sitting House member is affiliated; 0 otherwise). | | new_incumbonly | Incumbent-only New Democrat Coalition indicator in that Congress (1 if the sitting House member is affiliated; 0 otherwise). | | tea_incumbonly | Incumbent-only Tea Party Caucus indicator in that Congress (1 if the sitting House member is affiliated; 0 otherwise). | Dataset Context: This panel links U.S. House candidates to their party identification, recorded ideology from roll-call voting, affiliations with major ideological congressional caucuses, and election and donor environments over the 97th–113th Congresses (1981–2014). Roll-call ideology is drawn from widely used spatial scaling procedures: DW-NOMINATE provides a common scale across time, while Nokken–Poole estimates are produced separately within each Congress to capture short-run movement. Caucus affiliation indicators reflect publicly documented rosters of congressional membership organizations that articulate ideological or brand-like identities within each party. Rosters were compiled from official congressional registries of Member Organizations, reference volumes that track congressional activity, archived faction webpages, interviews, and contemporaneous reporting. Many ideological caucuses began or expanded in the mid-1990s and 2000s as the House formalized procedures for registering member organizations. Election results come from administrative and research consolidations of Federal Election Commission returns and related archives, providing general- and primary-election vote shares. District presidential vote share aligns each House district with the most recent presidential election result to summarize local partisan leanings. Donor-ideology measures are constructed from the Database on Ideology, Money in Politics, and Elections (DIME). Individual donations, PACs, party committees, and organizational contributions are linked to recipients and mapped onto a common ideological scale (CF-scores). For each candidate-by-Congress, the dataset summarizes the ideological composition of contributors using both the mean and median CF-score, allowing analysts to characterize the donor pool associated with a candidate in a given two-year period. Together, these sources create a candidate-by-Congress panel suitable for studying ideological positioning in the House, participation in intra-party caucuses, and how electoral and donor environments vary over time within the institutional setting of congressional sessions.
