Many Americans have been politically active on social media, from encouraging others to take action to using issue-related hashtags. And liberal Democrats were more likely than other ideological and partisan groups to have engaged in these activities, according to a new Pew Research Center analysis of survey data collected this summer. Liberal Democrats are especially likely to use social media to mobilize others or find like-minded groups. Some 44% of liberal Democrats say they have used these sites in the past year to encourage others to take action on an issue that was important to them, while a similar share (43%) have taken part in a group that shares their interest in a cause, according to a survey of U.S. adults conducted May 29-June 11, 2018. These shares fall to around a third or fewer among conservative or moderate Democrats and among conservative, moderate or liberal Republicans.
