Longitudinal modeling shows party satisfaction outweighs leader approval fourfold in driving vote intentions, indicating leadership changes offer limited long-term electoral gain.
This paper investigates the extent to which changing the leader will help Labour to win back support in the polls. It models public attitudes to incumbent parties, prime ministers and leaders of the opposition as determinants of vote intentions over a period of twenty‐eight years. The findings show that voter satisfaction with parties is nearly four times more important than voter satisfaction with prime ministers when it comes to influencing the vote. This means that changing the Labour leader is likely to have only a limited impact on support for the party in the long run.
