Yes I do. That's why I think it would be a good thing if they came up with a legitimate reason to have a second referendum. Now that people have a better understanding of the negative consequences of leaving the EU they would be in a better position to make an informed decision.
Yes, the British people voted out. Well, to be strictly accurate, slightly over half of the British people who voted did. If there were to be another vote -which seems unlikely but there is a growing movement pushing for one-, I suspect those who didn't vote the first time, along with the Brexiteers who've changed their minds, would make remain more than likely.
