I am also voting leave.
I also have no hope of this happening, but I consider the EU to be part of an entity that has warped too far since the country joined in the first place. Any organisation that can alter constitutional integrity without the express permission of the populace (Lisbon treaty, do NOT get me started on the implied consent by mere membership of the Union and the government at the time being pro EU, it's too tenuous, it is undemocratic as shown by the way it was pushed through regardless of referendum objection in other states) is simply not right.
We need to dictate our own destiny, the current world environment is too volatile to allow us to be exposed to group policy from an uneven whole. It is not an objection to Europe per sé (But yes, it has become too much), but a yes to greater flexibility in how our nation determines itself.
