3. METHODOLOGY
3.1 Operationalization of actor lists
I extracted publicly available Twitter lists from @gov, @cspan
and a collection of influential news media accounts from Daniel
Romero1 as a starting point for generating the actor lists [9]. These
were significantly cleaned and expanded by hand in order to cover
every member of U.S. congress with a Twitter account, all
governors, party accounts as well as accounts belonging to the
U.S. government and its officials. To add additional data of
lawmakers, the politics list was matched with a database of
GovTrack. To restrict the category news media to elites, only
media accounts officially verified by Twitter were included, while
individual journalists were excluded.2
