Raising a big tent: Internal party composition and leadership selectorate expansion

The trend amongst many parties toward the inclusion of rank-and-file members in the leadership selection process has often been attributed to opposition status and electoral defeat. However, these explanations are typical events for parties and hardly seem sufficient for party elites to willingly cede their authority over the selection of party leaders. This paper proposes that the electoral regionalization of the party contributes to the decision to expand the leadership selectorate. In the event a party is defeated to an extent in which their support is reduced to its regional base, this situation necessitates the bringing in of new voices to avoid further marginalization. This paper finds that regionalization plays a significant role in the decision of parties to expand leadership selectorates and that the role of opposition status and electoral setbacks have been overstated.
