“…We follow previous research in identifying five news factors that are particularly important for coverage of political actors (see Helfer & Van Aelst, 2016;Hopmann et al, 2012;Tresch, 2009): political power, negativity, surprise, relevance, and continuity. First, we expect messages by powerful politicians to have higher chances to make the news than those sent by actors without a powerful position (Balmas, Rahat, Sheafer, & Shenhav, 2014;Entman, 2007;Galtung & Ruge, 1965;Gans, 1979;Helfer & Van Aelst, 2016;Tresch, 2009;Van Aelst, Maddens, Noppe, & Fiers, 2008;Vliegenthart, Boomgaarden, & Boumans, 2011). Second, the media is particularly attentive to stories that include negativity and conflict (e.g., Ansolabehere & Iyengar, 1995), so campaign messages that satisfy the media's demand for conflict and aggression should carry a higher news value (Gans, 1979).…”
