John McDonnell was first with the theory, as soon as the exit poll had stunned the nation. “Brexit dominated the election,” he said. “I think people are frustrated and want Brexit out of the way.” The theme was taken up over the hours and days that followed, culminating in the claim Labour “won the argument” and that Jeremy Corbyn’s leadership had nothing to do with the party’s worst result since 1935. Brexit alone was to blame.
Well, if this is the result you get when you win the argument, we can only imagine what losing it would look like. But what about the idea that the result can be put entirely down to Brexit, rather than the broader questions of policy and leadership that usually go into people’s voting decisions?
I surveyed over 13,000 people on election day who had already cast their vote, to help understand how this extraordinary result came about. The results show who voted for whom, and why.
The final round of my general election polling dashboard, based on 4,046 interviews between 5 and 9 December, shows clear Conservative leads on most measures – but with Labour support continuing to harden at the expense of the Liberal Democrats as polling day approaches.
My latest 4,000-sample poll, conducted between Friday and Monday, finds little change in the overall picture, with Labour continuing to do better among its former voters than was the case at the start of the campaign.
My third general election survey shows the Conservatives still ahead on the fundamentals, but there is some evidence that Labour is managing to firm up its vote among 2017 supporters at the margins, with Labour Leavers showing slightly more reticence about switching to the Tories.
