The thesis demonstrates changes in the dynamics of competition, offering evidence that between 2006 and 2020 ideological differences between candidates proximate to competing factions became the dominant narrative in congressional primaries, first in the Republican and then in the Democratic Party. I consider causes of this development and implications in terms of the selective and adaptative polarizing effects, empirically testing if primaries reward ideologically extreme candidates in the 21^st century. Taking a contest-centered approach, the thesis foregrounds the dynamics of and reasons for primary competitions to better understand the implications for inter-party polarization. In doing so, the thesis demonstrates that trends of intra-party factionalism during the congressional nomination process influence partisan polarization.
