I think that the limitations of straightforward referendums where 50.000001% of the vote wins it for you have been exposed in the past couple of days, but that's the system we had and everyone knew it beforehand. So, for me at least, petitions for second referendums just come over as sour grapes - we've got a result after a turnout that was much bigger than in recent general elections and now we have to live with it's consequences.
