Labour's refusal to oppose Brexit is becoming a historic error [View all]
The attitude of Corbyn loyalists is that Remainers have nowhere else to go besides Labour. If Labour enable Brexit, this will have no noticeable impact on how Remainers vote in any general election. They dismiss a poll that suggests Labour could lose a large number of votes by attacking the poll: it was funded by the Peoples Vote campaign, and who believes polls? A more thoughtful criticism is that you are bound to get a large number in any question who highlight Brexit, but general elections will be fought over many issues. In short, Remainers on the left will always vote Labour.
I would agree that one poll tells you little about any future general election, but what it does reveal is the intensity of feeling over the Brexit issue. I think many among the Labour leadership and Corbyn loyalists fail to understand this. They prefer instead to misplace Remainers as the centrist enemy, and see attacks on Corbyn over Brexit as just one more means by which the centre and right of Labour attack Labour. This is a serious mistake.

They are assuming that young remainers won't vote Tory, they are not wrong. However if they assume that they will turn out for Labour they are taking a big risk
