There are two popular reactions to the Hartlepool by-election, which one you favour depending largely on your political tribe. The first holds that the white working class has reacted against a woke, metropolitan Labour party and its knee-taking leader, Keir Starmer. The second holds that the town’s racist and xenophobic population are still fearful that their beloved Brexit might yet be undone, and were desperate to vote against a Labour candidate who had backed Remain.
