I have never voted in my life, I have never seen a candidate worry of my vote. I feel cheated by democracy as it doesn't take account of those of us who choose not to vote for any of the candidates on the ballot paper. Political parties don't need to put forward a person who will capture the imagination of the electorate, they just need to put forward someone who is marginally better than the other parties are putting up. Democracy isn't democracy until it takes account of the people who don't vote.
The presidential race will be a choice between Clinton and Trump, most Americans wouldn't choose to choose between these two for President.
Like most political competitions it is a choice between the least worst. I believe that if less people choose not to vote than do vote for the winning candidate then the election should be declared null and void and the parties should be made to put up better candidates, ones people want to vote for.
