Replication Data for: Keeping One’s Seat: The Competiveness of MP Renomination in Mixed-Member Electoral Systems

Mixed-member electoral systems are supposed to simultaneously produce coherent parties and ensure the representation of local interests. We regard the competitiveness of MPs’ bids for renomination as a crucial indicator of the degree to which MPs are punished when deviating from their principals. Capitalizing on the opportunities offered by mixed-member electoral systems, we develop a theoretical account that makes the competitiveness of the candidate selection process conditional on the characteristics of the electoral system, the candidate selection regime, an MP’s parliamentary behavior, district characteristics and government status. Corroborating our expectations, the analysis of the candidate selection processes in the run-up to the 2013 Bundestag election shows that an increasing degree of ideological deviation from the party line—as expressed in parliamentary speeches—results in a worse position on the party list for opposition MPs, but does not affect the renomination chances of district candidates or of list candidates from the government camp.
