Romney's social media team did well when it practiced its strategy carefully before big events like the debates. But Obama's social media team was often quicker to respond to things and more creative. According to Kress, at extraordinary moments campaigns can exercise what Isaac Reed calls "performative power," influence over other actors' definitions of the situation and their consequent actions through well-timed, resonant, and rhetorically effective communicative action and interaction. During the Romney campaign as many as 22 staffers screened posts for Romney's social media accounts before they could go out. As Romney's digital director Zac Moffatt told Kreiss, the campaign had "the best tweets ever written by 17 people. ... It was the best they all could agree on every single time."
