Voting Advice Applications - VAAs - have become a widespread online feature of electoral campaigns in Europe, attracting growing interest from social and political scientists. But until now, there has been no systematic and reliable comparative assessment of these tools. Previously published research on VAAs has resulted almost exclusively in national case studies. This lack of an integrated framework for analysis has made research on VAAs unable to serve the scientific goal of systematic knowledge accumulation. Against this background, Matching Voters With Parties and Candidates aims first at a comprehensive overview of the VAA phenomenon in a truly comparative perspective. Featuring the biggest number of European experts on the topic ever assembled, the book answers a number of open questions and addresses debates in VAA research. It also aims to bridge the gap between VAA research and related fields of political science.
