In this multi-platform, comparative study, we analyze social media messages from political candidates ( N = 1,517) running for Congress during the 2022 U.S. Midterm election. We collect data from seven social media platforms: Facebook, Twitter, Truth Social, Gettr, Instagram, YouTube, and Rumble over the 4 weeks before and after election day. With this unique dataset of posts, we apply computational methods to identify messages that sought to mobilize individuals (online and offline) to donate money, vote, attend events, engage with the campaign online, and visit the campaign’s content on other platforms. We find that Democrats were not on alt-tech platforms in 2022 and that both Republicans and Democrats use video-based platforms for multiple mobilization strategies. Mobilization messages varied for House and Senate candidates of both parties across platforms, before and after election day.

候选人发帖：2022 年美国中期选举中的多平台策略和党派偏好

在这项多平台比较研究中，我们分析了 2022 年美国中期选举期间竞选国会的政治候选人 （N = 1,517） 的社交媒体信息。我们从七个社交媒体平台收集了选举日前后 4 周的数据：Facebook、Twitter、Truth Social、Gettr、Instagram、YouTube 和 Rumble。借助这个独特的帖子数据集，我们应用计算方法来识别试图动员个人（在线和离线）捐款、投票、参加活动、在线参与活动以及访问其他平台上的活动内容的消息。我们发现，民主党人在 2022 年没有使用另类技术平台，共和党人和民主党人都使用基于视频的平台来制定多种动员策略。在选举日之前和之后，两党众议院和参议院候选人在各个平台上的动员信息各不相同。
