Party Politics, Ahead of Print.
Institutional configurations in multilevel states create tensions in political decision-making processes resulting from constitutional decisions. Often, these decisions affect party competition, e.g., a member of the parliament (MP) may be legally bound to represent they constituency or the entire territory yet be elected regionally. In these settings parties place their members in additional positions thereby gaining advantage. Does former experience as a regional MP increase the probability of becoming a national MP? We expect that MP candidates from regional constituencies are more likely to have legislative experience in the regional assembly. We test our expectations with novel data from Portugal and demonstrate that candidates who were regional MPs are more likely to be in eligible positions and to take office. Conversely, former regional government members (elected officials) have a negative likelihood of becoming a national MP.
