It will ensure that people understand what they are voting for and not just voting for someone who has a nice smile on TV.
I'm fed up with hearing that people have voted for someone because he has a nice smile or because they always vote that way. Lets take this opportunity to introduce a quick few questions on what the different parties are including in their manifesto to ensure that people voting know what they are voting for. An independent body can establish the questions to ensure no bias on them and everyone answers a few and then votes. However, if they get a % of the questions wrong their vote is not counted, if they pass their vote qualifies. It still leaves voting open to everyone, but people have to ensure that they are suitably informed to make a decision which shapes the future of our country.
