   Among states with razor-close gubernatorial elections, what is the average effect of having a Democratic (vs. Republican) governor on the subsequent change in the Democratic share of the two-party presidential vote in that state?

   | Variable Name | Description | |-----------------|-----------------------------------------------------------------------------------------------------------------------------------------| | (index) | Row identifier from the CSV export; sequential numeric index with no substantive meaning. | | pres_change_reg_1 | Change in a state’s Democratic share of the two‑party presidential vote from the previous presidential election, demeaned by election year; percentage points. | | rv | Democratic margin in the most recent prior gubernatorial election (Democratic two‑party share minus 50); positive values = Democratic win, negative = Republican win; percentage points. | Data Description: This file is a state–year dataset assembled from historical U.S. election returns to examine how party control at the state level relates to subsequent presidential voting patterns. Each row corresponds to a state in a presidential election year and includes the shift in that state’s Democratic two‑party presidential vote relative to the previous presidential contest, along with the Democratic margin from the preceding gubernatorial election. The subset shown here focuses on cases where the prior gubernatorial race was close (roughly within ±5 percentage points of parity). Election data were compiled from the Inter‑university Consortium for Political and Social Research (ICPSR) archives and official publications of state election authorities, following the paper’s coding conventions: vote shares are recorded as Democratic two‑party percentages, changes are computed across presidential cycles, and margins are centered at 50 percent. The broader study spans elections from the late 19th century through 2012; values are reported in percentage points and are suitable for reproducing the specific specification referenced in the paper.
