The included fields capture (i) whether the member signed any pro\u2013civil-rights discharge petition during the 88th Congress, (ii) the district\u2019s Democratic two\u2011party vote share from the immediately prior House election, and (iii) the member\u2019s ICPSR identifier.\\n\\nThe underlying study assembled archival evidence on discharge petition signatures from the National Archives (covering 1933\u20131976) and linked those signatures to legislators. Election returns were matched using standard historical House election datasets, and member identifiers come from ICPSR. The broader research situates these data within an effort to trace how members advanced civil rights outside of roll\u2011call votes\u2014particularly through discharge petitions that could bring bills to the floor despite committee gatekeeping\u2014providing insight into party coalitions and legislative activity during 1933\u20131972.\\n\",\n \"columns\": {\n  \"petpooled\": \"int64\",\n  \"Dvotespercent\": \"float64\",\n  \"icpsr\": \"int64\"\n }\n}"}
