There's a consistent anti-labour vote of ~14,000-24,000 but it moves around quite a lot, supporting the party that seems best placed to depose Labour. Tory in 2017, UKIP in 2015, LD in 2010
Hartlepool does have its widely despised and venal leadership of the local Labour group - even by the normal loathsome standards of local government. This drives a lot of anti Labour sentiment in the town which would otherwise not exist.
