It’s late afternoon in the car park of Workington Asda. A little crowd is gathering in one corner, most of them clutching cameras and tripods. We’re not here to find ‘Workington Man’, the supposed archetypal voter who apparently all the parties need to court to win this election. Instead, Workington men and women — and a number of us from all over Cumbria — are here to watch a bunch of birds going to bed.
