Allow me to draw two different mental images.
In a college town somewhere in the midwest, there are two 20 year-old students who got together to share an apartment. They are responcible for just themselves and whatever things they might wish to buy. At election time, they get two votes.
In a suburb not too far away, there is a married man and woman. They have five children, age 13, 10, 9, 5, and 2. They have the duty to raise these children — not a light burden, in addition to providing the material needs for a family of seven. At election time, they get two votes.
I call this electoral fraud.
Consider this: The number of votes per household rightly should depend on the number of people in the household. Clearly, in our example, the household with the dad, mom, and five children has more — much, much more at stake in what happens as a result of an election. A man is not free unless he is free to represent the interests of every one of his children equally.
