When Parties Swing: Islamist Parties and Institutional Moderation in Malaysia and Indonesia

This article examines the extent to which the Malaysian Islamic Party (PAS) and the Prosperous Justice Party (PKS) are becoming more moderate in their strategy and ideology. The author contends that both parties are struggling over the extent to which they should moderate in response both to strategic incentives present in the Malaysian and Indonesian political systems and to the political learning process whereby both parties are coming to understand the preferences of voters in their respective political systems. This process is complicated by divisions in the parties between pragmatists who would postpone controversial goals to reach out to non-devout voters, and purists who prioritize ideological authenticity.
