Abstract

Previous work on candidate campaign finance in list proportional representation systems has focused on differential electoral returns of spending for incumbent and challenger candidates. This article asks whether incumbents and challengers in these systems fund election campaigns from different sources. We hypothesize that incumbents receive more: (a) contributions from individual and corporate donors; and (b) financial support from party organizations, as party elites strategically deploy resources to constrain intra-party competition. The analysis is based on a dataset on campaign funding sources of candidates for two legislative elections in Colombia (2014 and 2018). The results confirm that party organizations transfer more financial resources to incumbents than to challengers. Contrary to expectations, parties do not specifically support the electorally most vulnerable incumbents. We also find that challengers receive higher levels of non-corporate private donations than incumbents. These findings provide insights into individual campaigns and demonstrate how parties coordinate intra-party competition through campaign funding.
