The question hasn't changed at all. The losers just will not accept the result.
The question has changed.
The original question was, Do you want to leave and save £350 Million/ Week, have the same trade deal with the EU, open up new trade across the world, have greater control of our borders and many other benefits.
The new question is, do you want to leave, save nothing, spend an extra £8.5 Billion trying to limit some of the damage caused by leaving, have no trade deal with the EU, secure very little new trade across the world, have roughly the same controls at our borders, lose thousands of jobs, devalue the pound, and many other disadvantages.
There is so much difference between the two questions that the only democratic way forward is to ask the new question and see what people say. If you are correct, then leave will win again. You talk a lot about democracy, so you will agree with what I have written.
