Conventional wisdom suggests that presidential nomination campaigns are inherently divisive and that the intraparty division fostered during the nomination campaign continues into the general election contest. Division occurs within the party between those preferring a nomination winner, the in-group, and those preferring a nomination loser, the out-group. This study examines in-group/out-group relations during the 1980 presidential nomination and general election campaigns. The author found clear evidence of intraparty division during the nomination period. However, during the general election the in-group/out-group relationship is ameliorated The author suggests that the institutional process, moving from a nomination to a general election campaign, helps to reduce factional division among the party's rank-and-file membership.
