Getting Brexit done? The politics of issue-eclipsing pledges
研究了政策承诺与选举动员之间的冲突，以英国脱欧为例，说明议题遮蔽承诺如何导致政治激进化和路径依赖，对理解选举策略和政策执行的关系有帮助。
Leaders are rewarded for delivering on policy pledges. Yet mobilisation strategies often depend on keeping issues and unsolved problems ‘alive’ for electoral purposes. What happens when these incentives collide has been subject to little attention. Drawing on the example of Brexit in the United Kingdom, this article examines the politics of issue-eclipsing pledges – scenarios in which policy pledges directly undercut mobilisation strategies. Brexit offers a good example of these tensions because the referendum vote called the bluff of decades-long Conservative efforts to instrumentalise EU membership for electoral gain. We show how issue-eclipsing pledges produce cyclical and path-dependent dynamics that tend towards radicalisation, as pledges of incumbent elites to guarantee policy delivery are vulnerable to the efforts of non-incumbents to re-interpret pledges and re-mobilise bases of electoral support. We illustrate these dynamics by narrating the interplay of reform pledges and re-mobilisation strategies encountered by successive UK governments since the 2016 referendum.
