I think if we split the leave vote we should also split the remain vote
i.e.
Hard Remain - Full in on euro, push for harder, deeper integration like common defense force, cede more power to the EP
Soft Remain - Pretty much status quo, no changing current course of the EU
Reform Remain - Stay a member but use the veto to enforce some reform of the EU in the direction more in line with UK popular opinion (allowing greater control over immigration, ability to opt-out of directives and so on)
That would help even things out a bit, but as a PP has said it has become such a political football, and now with JC hinting he make back a second referendum and the CLP caring more about Palestine than Brexit it shows how much of a shit show it all is.
