Brexit too important for party games? Yes it is. Unfortunately that is the only way any party can think of it. I was chatting to someone a while ago about patriotism since this os often claimed as well. I claimed that when an action benefits both your self interest and the country it could be done through patriotism or self interest and there is no way to tell. You may even delude yourself. In an Occams razor sort of way, the concrete self interest is probably a more ppwerful force than the abstract patriotism.   So to be a cleaely patriotic act your self interest and the countries interests must be opposed and you must act against ypur self interest to the benefit of the country. That is why a soldier can be patriotic as being killed or severely wounded is not on their personal interest. You could defend higher taxes on the grounds of patriotism if you are personally worse off but think it is right thing to do; you cannot defend a change that lowers taxes for you in that way.

So all that chat is leading up to this: politician, name me something you are striving for in Britain's interests that is opposed to your individual and party interest. If you can't you cannot demonstrate you have any stronger motivation than self interest.
