It was part of the Conservative's election manifesto to enable a referendum of EU membership; enough people voted Conservative for them to form a government therefore they are enacting their manifesto. It wasn't a knee jerk reaction by Cameron over the last year; it's been something brewing for many many years. If Cameron resigns because of a leave vote then it is highly unlikely there will be a general election as a result. Conservative party members will vote for the next PM at party conference, not the general public. So Boris won't need _your_ vote to become PM, haircut or not.
