If another referendum was held next Thursday I have no doubt the IN campaign would win hands down. So many Brexiters have admitted they didn't think they would win and now that reality is starting to bite, I think they would vote differently.
However, there is not going to be a second referendum. It's a pity that rules like, the majority has to be at least 60%, weren't put into place before last Thursday, but there it is. We can't change the rules just because we don't like the outcome.
Yes, it's going to happen but I think it's a great shame that the fact that the UK was due to take over the EU presidency in July of next year, where we could have started a revolution to change the EU, was not even mentioned (as far as I know) by the IN campaign.
The referendum is not legally binding so our only hope is that parliament don't implement it. Then all hell will break loose.
