Poland held elections to its parliament in September 2005. Its lower house, the Sejm, is elected proportionally from closed lists. The Senate is elected in two- or three-member winner-take-all districts. While this feature of Senate elections should discourage small parties from running candidates, more and more parties contest elections with each passing cycle. Despite a relatively high threshold of 5% to enter the Sejm, small, ideologically similar parties proliferate, and coalition-building remains a challenge. This paper looks the intersections of Poland’s electoral system and party behavior, coalition-bulding, and turnout. It also considers the potential implications of a change to the formula used to allocate Sejm seats.
