I think that the internationalism is the thing that people are pissed off that we feel has been sold out on both sides. The EU didn't push that, they pushed a load of economic bullshit which they were going to push whatever the result at some point in time. But the Leave campaign didn't push that either, the UKIP were far more vocal and recognisable than any sort of internationalist movement and the idea that this is going to get rid of them is more pie in the sky than the idea that the EU would get through it's own crises somehow by default
Nobody has the right to claim a victory, that is why nobody has. There were much better referendums to have and take to the EU, save Greece, deal with the crisis in the Med, deal with unemployment in France and South Europe, have a referendum on that, not 'Get rid of David Cameron
