Men as a group have fewer voting rights than women as a group. I'm not kidding here. This isn't just a matter of women having more members in the population. Nor is it a matter of women voting more proportional to their sex. I repeat men as a group have fewer voting rights than women as a group. The logic is simple. Prisoners often enough don't have the right to vote.

Should all men have the right to vote?

Is the denial of the right to vote to prisoners a means of trying to divide the male voting block?
