The A, B, C of voting in an election

How come the Nationalist and Labour parties have never done anything to rectify the unfairness of having names listed on ballot papers alphabetically? All candidates whose surnames start with the first letters of the alphabet are obviously at an advantage as most people go from top to bottom when they vote in support of a particular party. This is really unfair and discriminates against other candidates. It gives some candidates an opportunity they do not deserve and puts other, perhaps smarter ones, off.
