The Electoral Constraints on Inter-Party Mobility of Candidates: The Case of Pakistan
This article investigates the electoral constraints on the inter-party mobility of candidates. We argue that the prevalent mode of interactions among candidates, voters, and parties in local, district-level electoral markets shapes the strategic constraints faced by potential party switchers. We suggest that strong linkages between voters and political parties reduce the market value of the candidates outside of their political parties, thereby constraining their inter-party mobility. These expectations are evaluated using candidate- and district-level data from Pakistan from 1988–2013. The results show that the strength of voter-party linkages in an electoral district, as measured by the lack of electoral volatility and the extent of straight-ticket voting in national and provincial elections, has a positive effect on the propensity of candidates to switch parties.
