The relationship of digital media platforms and public participation in election campaigns was investigated through an original survey of randomly selected registered voters. The goal was to produce a better understanding of how exposure and attention to political news on different digital platforms were associated with participatory behaviors and to test whether the association of participation and digital news was moderated by online political expression as predicted by the differential gains model of political engagement. Among platforms, news websites, Facebook, and Twitter produced the strongest positive relationship with online expression, while news websites and mobile news apps were the strongest predictors of off-line participation. Online expression was significantly related to participation, and enhanced digital news use’s association with participation across platforms. These results hold practical implications for journalists to better understand how to allocate resources across digital platforms, anticipate audience interest, and engage with digital news users during election campaigns.

通过对随机选择的注册选民的原始调查，调查了数字媒体平台与公众参与竞选活动的关系。目标是更好地了解不同数字平台上政治新闻的曝光度和关注度如何与参与行为相关联，并测试参与和数字新闻的关联是否如差异收益模型所预测的那样受到在线政治表达的调节。政治参与。在平台中，新闻网站、Facebook 和 Twitter 与在线表达产生最强的正相关关系，而新闻网站和移动新闻应用程序是最强大的离线参与预测因素。在线表达与参与显着相关，并增强了数字新闻使用与跨平台参与的关联。这些结果对记者具有实际意义，可以更好地了解如何跨数字平台分配资源、预测受众兴趣以及在竞选期间与数字新闻用户互动。
