HelpMeVote/VoteMatch is the Greek Voting Advice Application that was used for the 2014 elections for the European Parliament as part of project Vote Match Europe, an international network across fourteen EU countries: Germany, the UK, Belgium, Poland, Latvia, Greece, Bulgaria, Austria, Italy, Spain, the Czech Republic, Slovakia, France and the Netherlands. Vote Match aims to be fun but it also aims to encourage turnout, inform voters about policy differences between parties, and foster informed debate on political issues. It has the potential to promote European citizenship and to better inform citizens about elections for the European Parliament (EP). Vote Match is a tried and tested tool which reaches millions of users.
