The following bachelor thesis is, with the help of Gender Role Congruity Theory of Prejudice and Gender Communication Style theory, analyzing the case of Hillary Clinton in relation to masculine and feminine leadership style. More specifically, it examines 1) To what extent is Hillary Clinton adopting a feminine or masculine leadership style during the 2008 campaign? 2) To what extent is Hillary Clinton adopting a feminine or masculine leadership style during the 2016 campaign? 3) Are there any changes in her approach, given that she lost the nomination in 2008 and won in 2016? The thesis is a single case study with a qualitative content analysis. The data selection which is analyzed in the research constitutes Hillary Clinton's transcribed campaign remarks from her two presidential election campaigns, 2008 and 2016. Our research concludes that Hillary Clinton uses a rather mixed leadership style during both campaigns. Although, we can conclude that Hillary Clinton's general leadership style shifted from being more influenced by masculine traits in 2008 to slightly more feminine traits in 2016.
