How do voters make electoral choices? Answering this supposedly simple question is actually one of the most complex endeavors in electoral research. There has been substantial research output over the last 80 years with a number of traditions (e.g., sociological, social-psychological, or rational choice) being developed and refined (for an overview see van der Eijk and Franklin 2009). Among other things, these attempts at explaining vote choice have one assumption in common: that voters at large are informed about the electoral processes, party preferences, and their own preferences. Quality, quantity, and sources of information may vary regarding the different explanatory approaches. Nevertheless, an important strand in the literature has therefore examined the relationship between information and electoral choices-a strand that we investigate and extend in this special issue.
