"Part of Cameron's problem is that he was excessively influenced by his experience of the 2014 Scottish independence referendum, when he put his premiership on the line for another knife-edge, in/out, winner-take-all vote, and won. But the Brexit referendum was different and in refusing to acknowledge the differences he ended up losing everything. As far as I can see, two things went wrong. In one crucial respect, Cameron failed to follow the formula that served him so well in Scotland. Separately, he failed to appreciate that an in/out vote, which suited his purposes in Scotland, was a big mistake for the question of EU membership. This mistake didn't just cost Cameron his political career. It cost the country its political sanity."
