Party Politics, Ahead of Print.
Many Western parties have opened up the process of leadership selection in order to increase the party’s attractiveness, but negative reactions of losers in such contests might undermine these efforts. It has extensively been documented that losers of elections or referendums become less supportive for the political system, but the question is whether such a winner-loser gap also occurs in the context of intra-party elections. We examine unique panel data collected before and after the leadership elections of the Flemish Christian-Democratic Party and Liberal-Democratic Party and investigate the difference in change in attitudes and behavior of party members who voted for the losing candidates and those who voted for the winner. Contrary to earlier research on candidate selection, we find that only decision acceptance differs between winners and losers, while there is no gap in support for the electoral process, party membership satisfaction, and members’ activity within the party.
