And
@Redlambs as you've replied to the post. Bishop is an odd constituency with a lot of weird demographic stuff going on. Bishop Auckland itself was a working class town surrounded by old pit villages and has had the typical industrial town story - since the 60s it's been in heavy decline with the death knell for industry coming in the Thatcher years. In recent years the centre and the farming villages towards the Pennines have seen a bit of an upturn, largely because they've started building shitloads of commuter/retirement houses, whilst the pit villages and the outskirts of the town have been left to rot. 'Emigration' rates of young folk are high because there's balls-all there for them, whilst 'immigration' of middle class commuters and retirees is common because outside of the places which show the scars of industry it's a really beautiful area. Barnard Castle and the area around is an especially desirable place to live and has always been a Tory enclave. Overall, the constituency is the sort of place where continued Labour pluralities have increasingly relied on the continued loyalty of their core vote holding up to steady things against a growing number of Tory and swing voters. That was already crumbling as nothing really got better under Blair's government, but Brexit hasn't helped and the Corbyn factor was likely in play as well. On top of that, the incumbent MP was deeply unpopular. She got caught in the expenses scandal, did feck all for her constituents
and once opened an event in a small village called Ingleton with a speech waxing lyrical about Ingleton's beautiful waterfalls and caves having googled the wrong Ingleton. When I was campaigning in Bishop I was specifically advised not to mention her because even in Labour circles she was disliked.
