The US Senate is increasingly targeted by left-wing think tanks and legislators for the fact it is based on “voter inequality.”
According to critics, the Senate ensures small states are “overrepresented,”and the body favors voters in smaller and more sparsely populated states. In contrast, reformers hold up the concept of “one man, one vote” as an ideal and a solution.
“One man, one vote” is not a clearly defined concept, but it is often used to oppose legislative schemes used in federal political systems. Among these schemes is the US Senate in which each state is given an equal vote so as to balance out the interests of small states against the interests of large states. Large states, of course, dominate legislatures in population-based representation systems like that used in the US House of Representatives.
