The Winner Premium

Political actors often treat election outcomes as binary, regardless of the margin: winners celebrate and mobilize, losers mourn and withdraw. Even when rank conveys little information about underlying support, this asymmetric response can have consequences for political fortunes. This paper develops a framework in which the salience of rank—winning versus losing—leads to differential political investment, converting narrow and potentially arbitrary electoral outcomes into persistent political advantages. I study this winner premium using counties in presidential elections, where winning carries symbolic importance while affecting neither the national outcome nor any local office or policy. Focusing on a period of intense partisan realignment between 1940 and 1968, I find that counties where Democrats narrowly won the presidential vote subsequently saw pronounced increases in Democratic local officeholding and voter support. These effects operate through political investment, including voter-registration advertising, direct voter outreach, and civil-rights organizing, with the largest effects in urban, Black, and union areas. The findings suggest that elections do not merely reveal political support, but also direct the investment that helps produce it.
