This article seeks an insight into the nature of intraparty competition in an open-list single preference voting system, and it does so by analysing the distribution of votes for Centre Party candidates in the 40 or so municipalities making up the northern Finnish constituency of Oulu in each of the five general elections between 2003 and 2019. It builds on Grofman’s distinction between a geographical constituency and a candidate’s electoral constituency to map the ecology of candidate support in a constituency with (1) a larger than average district magnitude (M); (2) a significantly larger than average territorial magnitude (T); and (3) a substantially larger than average Centre party magnitude (P). Setting M, T and P within a party organisational framework, the article identifies (1) a significant disparity between levels of intraparty competition at district and sub-district levels; (2) several contextual factors that act more as disincentives than incentives to engage in personal vote seeking across the electoral district.
