They should hurry up and do it. The people were clear, deal or no deal. Actually there have technically been 2 deals now and that wasn't even part of the initial question.
When they voted yes, I remember some American in my office complained that English people are all stupid, Then I told, nope, it's just a popular choice and the media lies, and to wait until Americans elect Trump and she got really angry with me.
Then Americans elected Trump and I said, I don't think Americans are stupid either.
My point is the people aren't stupid, saying the people were mislead or something is ridiculous. The question was simple. No one understood the consequences. We couldn't even predict Hard Fork 21 completely and it is much much simpler.
The problem with democracy is populism does win and there is the chance of propaganda, but it's biggest strength is people can decide and we aren't ruled by people who think they know what is good for us.
