Applying AI-based methods to the universe of tweets po sted by members of the U.S. Congress (2017-2022)\, I measure the returns to offensive communication both in terms of online engagement and electoral s upport. I document that posting toxic tweets generates a sizable engagement premium and that these gains decrease with politicians' baseline toxicity. To examine how voters respond to offensive speech\, I link the timing of t oxic tweets to a large-scale electoral survey. Using an event study design around days marked by sharp spikes in representatives’ toxic tweeting act ivity\, I find that voting intentions for the politician increase in the fo llowing week. The increase is concentrated among ideologically aligned vote rs\, while opponents display lower electoral support\, widening the partisa n voting gap. These findings highlight the presence of both online and elec toral incentives to the production of offensive communication\, which comes at the expense of growing polarization.\\n\\nContact: Arthur Guillouzouic : arthur.guillouzouic-le-corff[at]univ-amu.frFederico Trionfetti : federi co.trionfetti[at]univ-amu.fr\n\nPlus d'informations: https://www.amse-aixma rseille.fr/fr/evenements/elliot-motte LOCATION:Îlot Bernard du Bois - Amphithéâtre\, AMU - AMSE\, 5-9 boulevar d Maurice Bourdet\, 13001 Marseille URL;VALUE=URI:https://www.amse-aixmarseille.fr/fr/evenements/elliot-motte CONTACT:Arthur Guillouzouic : \;arthur.guillouzouic-le-corff[at]univ-am u.frFederico Trionfetti : \;federico.trionfetti[at]univ-amu.fr TRANSP:OPAQUE END:VEVENT END:VCALENDAR
