Elections and Voters

First edition

by Cees van der Eijk and Mark Franklin

Glossary of terms

Elections and Voters makes use of a specialized vocabulary, introduced progressively in the course of the book, in which the words and phrases that constitute this vocabulary are often italicized on their first occurrence. Generally these words are not specifically defined but are used in such a way as to make their meaning clear without formal definition. This may require readers to peruse considerable amounts of text in order to fully understand the use of a word. In this glossary we define the terms more succinctly, to help readers who are dipping into the book rather than reading it from cover to cover, and to help students who are reviewing their understanding of the text. Each term is accompanied by a page reference at which what we consider to be the most useful account of the term can be found. However, the glossary should be read in conjunction with the book's index, which lists all the passages in which the term is used, since the glossary definitions are often insufficient to capture all nuances of meaning. Importantly, the meaning of some terms is contested, as mentioned in the book itself, in which case this glossary describes how we use them in the book, obviously without any claim that other analysts of elections and voters would fully concur.
