Microblogging sites such as Twitter play an important role in the transmission of news and opinion about economic, social and political events. There is, however, little guarantee that the content provides an unbiased account of the original events. In this paper we explore this issue by analyzing how the substantive and affective content of Tweets evolved throughout a series of important political events in 2015 and 2016: the Republican presidential primaries. We find that while the debates were in progress users Tweeted and retweeted a mix of policy-related and sensationalist topics, but that after the debates retweeting focused primarily on sensationalism. An analysis of content choice over time suggests that the persistence of such content was associated with a social diffusion process wherein sensationalist Tweets were most often initiated by “little voices” who had small followings and tended to post infrequently, then spread (through retweeting) by “shouters” who also had small followings but posted more actively, and finally were sustained after the debate by “leaders” with large followings who tended to Tweet selectively.
