How did the production and consumption of political information on Wikipedia mirror the dynamics of the 2016 U.S. Presidential campaign? Drawing on systems justification theory and methods for measuring the enthusiasm gap among voters, this paper quantitatively analyzes the candidates' biographical and related articles and their editors. Information production and consumption patterns match major events over the course of the campaign, but Trump-related articles show consistently higher levels of engagement than Clinton-related articles. Analysis of the editors' participation and backgrounds show analogous shifts in the composition and durability of the collaborations around each candidate. The implications for using Wikipedia to monitor political engagement are discussed.<\/jats:p>","DOI":"10.1145\/3359135","type":"journal-article","created":{"date-parts":[[2019,11,8]],"date-time":"2019-11-08T13:40:21Z","timestamp":1573220421000},"page":"1-20","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":3,"title":["The Dynamics of Peer-Produced Political Information During the 2016 U.S. Presidential Campaign"],"prefix":"10.1145","volume":"3","author":[{"given":"Brian C.","family":"Keegan","sequence":"first","affiliation":[{"name":"University of Colorado Boulder, Boulder, CO, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"320","published-online":{"date-parts":[[2019,11,7]]},"reference":[{"volume-title":"Social Media and Fake News in the 2016 Election.
