“…Early studies found that legislators' party membership, age, gender, and seniority determine who uses Twitter and how often (Jackson & Lilleker, 2011;Lassen & Brown, 2011;Hemphill, Otterbacher, & Shapiro, 2013;Peterson, 2012). More recent research on the members of the European Parliament (MEPs), moreover, shows that voting systems, district magnitude, and seat safety are also important factors (Obholzer & Daniel, 2016;Scherpereel, Wohlgemuth, & Schmelzinger, 2016); presence and activity on Twitter increase with the incentives that these factors create for individual legislators to cultivate a personal vote. With regard to the content, Twitter seems to mimic legislative communication practices in both form and substance, where legislators 'broadcast' their typical messages to voters in a way that leaves very little room for interactive communication (Golbeck, Grimes, & Rogers, 2010;Hemphill et al, 2013;Jackson & Lilleker, 2011;Saebø, 2011).…”
