The impact of ideological positions and personal attributes of candidates in intraparty competition: A study under the Swiss open‐listPRSystem

subject

description

Intraparty preference voting systems offer different incentives for candidates to cultivate a personal vote, but little is known about how the candidates' policy positions affect their elec-toral success in intraparty competition. This article analyses the effect of candidates' ideological positions and personal attributes on their preference vote share in the 2015 and 2019 Swiss Lower House elections. We used candidate survey data combined with official election statistics. Our findings demon-strate that the ideological distance between candidates' posi-tions and their party's median position is of minor importance for their electoral success when compared to their personal attributes. However, ideological distance between candidates and their party's median position reduce their preference vote share.
