Chapter 8 investigates postwar partisanship, first in enduring postwar election effects from local casualties, then in war memorialization, and finally in the partisan dynamics of Union veterans’ organizations. I describe the political aftermath of the war and test whether wartime voting patterns – including casualty effects – persisted after the fighting and dying ended. I find the massive scale of wartime death continued to shape local political voting patterns in postwar presidential elections for decades, a first in casualty-opinion studies. The chapter also shows how partisanship predicted which states were first to commemorate their dead on Decoration Day, to document their state’s war service in bureaucratic records, and to honor their veterans and the dead with local monuments. Chapter 8 also finds more chapters of the Grand Army of the Republic (GAR) veteran’s group in prewar Republican places, along with evidence of the GAR’s indirect impact on General Ulysses S. Grant’s 1868 election, when veterans organized actively to boost Republicans.
