@ccferrie So Romania has the concept of an unsafe result, as do Switzerland and Ireland. It's a shame that the UK and the US do not. Evidently "mature democracies" are incapable of believing that the electorate can be misled, regardless of any amount of evidence.
I think it's because the US and UK treat democracy as a religion rather than a practice. If it were the latter, it'd be subject to reasoned evaluation and review, whereas the former is a matter of faith and to challenge it in any instance is heresy.
