Abstract
This study describes e-mail use in the 2008 U.S. presidential nomination campaigns. A content analysis and rhetorical analysis of over 1,400 e-mails from the primary season of that campaign reveal evidence of typification. Consistent practices and shared purposes are evident in the campaign e-mails, along with shared and individual variations indicating an emergent communicative form. In-group identification pairs with interactive, supporter behaviors to make up the dominant constellations-of-practice within this corpus.
