Most studies on political actors’ use of Twitter focus on content and social network analysis, but not on their motivations and passive usage. We applied a questionnaire to a significant sample of 94 Members of Parliament (MPs), with a quota sample sized by political party representation in Parliament, to survey their motivations to have or not a Twitter account and their uses. We concluded that MPs see Twitter mostly as a political tool unlike other social media platforms. The most common motivation to join and use Twitter is to read other politicians’ opinions which helps explain why the small Twitter adoption in Portugal does not deter its use as their peers and political elite is on the platform. That twitter elite can even be a motivator to join as their peer social capital is key to re-election in closed list-elections countries such as Portugal.
