Abstract: | Abstract In this paper, we ask what sets of factors influence the timing and the content of presidential candidate press releases. Utilizing a unique data set, we examine the influence of internal campaign factors as well as external media factors on campaign information dissemination during the invisible primary season. We find that both types of factors may influence the timing of press releases; as to content, however, media norms are less likely to alter a candidate's general strategic message, which is dictated by his competitive status and national stature. |
