If we had one and they won again it would be the ultimate confirmation that it really is the will of the people.
By refusing to countenance it and describing it as a betrayal they may as well say it's not the will of the people anymore we're insisting on honouring something no one with any sense and without a vested interest wants and we should therefore call it off.
We're being forced into something the people who most support it clearly know is no longer the people's choice that's going to do horrible damage to the country. Just why can no one stop it???
