Can American state legislators use social media to influence the political behaviors and attitudes of the public by crafting strategic messages? While elected officials from every level of government use social media, it is not clear how the public responds to their individual posts. I argue that the rhetorical strategies employed by legislators can have a direct impact on their online constituencies, moderated by the existence of a copartisan relationship. I test my argument using a simulated social media environment embedded within a traditional survey experiment to mimic the impact of real-life social media posts. I find that legislators’ social media posts influence their approval ratings, and at times, the public’s trust in government. However, I do not find evidence that small numbers of social media posts affect a willingness to participate in politics.
