It includes measures of Democratic two-party vote shares for both House and presidential elections by district-year, indicators of election timing relative to November, and derived variables summarizing prior House results (e.g., margins, party control). Values expressed as vote shares are on a 0–100 percentage scale. The data were constructed from historical election returns compiled from authoritative sources on U.S. congressional elections and political parties, with presidential returns aggregated from county to congressional districts where necessary. The coding captures party identification of House winners, whether an election year coincided with a presidential contest, and whether districts’ House elections were held before, during, or after November. The dataset provides structured context for analyzing patterns in electoral outcomes and the institutional environment of nineteenth-century U.S. elections under party ballots.

   Pressupostos do estimador

   • the conditional mean of the outcome is linear in the regressors
   • errors are independent across observations; their variance may differ
