CHOICES PARTIES DEFINE.

Elections are the defining institution of democracy, in the sense of directly linking popular preferences to public policy. Which programme gets chosen depends on the outcome of the election. However, voters' choices are very much constrained by the policy packages parties put forward in the first place. In most representative elections, no alternatives can be voted on apart from those advocated by established parties, who thus play a role almost equal to electors in defining the election outcome. This article examines the policy choices offered by parties in their published programmes over 17 post-war democracies—uncovering a wide variety of patterns with only limited links to type of election system or number of parties. Voters always have a choice, though in some countries it is more limited and less nuanced than in others. [ABSTRACT FROM AUTHOR]
