This document analyzes political parties' use of websites and social media during recent elections in Germany, the UK, Poland, and France. It finds that parties have adopted a more interactive approach online, moving beyond just broadcasting messages. Parties now focus on persuasion and mobilizing existing supporters through their websites and social media platforms like Twitter and Facebook. Larger, more popular parties tend to have larger online followings and communities compared to smaller parties. The size of a party's online following on social media seems correlated with its overall level of electoral support.
