Now that it isn't being influenced by an outside party, it is no longer narrowly winning.
My original point about Brexit being very close still stands and I would suggest that your Remain on 52% and Leave on 48% are still very close given the sheer pain of the separation that has become apparent since the original vote (you try listening to the news here - its bloody boring.) If you had waved say 60% Remain, I might take notice.
