The are you intelligent to vote is a pointless debate - our justice system is based on a jury decision - we don't intelligence test juries - so if we have decided anyone over 18 can make a sound decision on whether someone is guilty of murder - then they also have the right and capability to vote. There is always to odd stupid person who says things like "I voted to leave because I saw a straight banana in the supermarket" but that didn't decide the results. My issue is the basic lies of politicians - the £350 million to the NHS claim was a lie - pure and simple - if it had been an advert by a company it would be banned but somehow it was allowed to be used throughout the election. Anyone can vote but unfortunately we appear to have got in a position now were outright deceit is seen as acceptable and people are making decisions on what they think is the truth but is a pure con. Yes you could say - well if they were cleverer then they'd know it was complete crap - but actually I think the responsibility should be with political parties not to come out with such rubbish. Yes spin stuff, gloss around the edges, it has always happened - but the £350 million claim was another level.
The EU and Scottish Independence referendums are a joke because it wasn't clear what you are voting for - nobody could define what would happen if we left the EU (customer market wasn't even mentioned) Scotland - nobody even knew what currency they would use - how can anyone possibly make a sound decision when you don't know what the impact is of one of the options on the ballet paper.
