As I've said before, we should come out and amend the constitution to make this a better country.
A short recap of previous amendments:
D1: The ERA
D2: Define Marriage and give federal weight to Civil Unions
D3: Let Congress protect citizens (end-run around the commerce clause)
To add to this list of good ideas that we really should consider, I'll add a fifth stolen right from The West Wing.
Amendment D5: Voting Rights
All citizens who reside in these United States shall be counted and persons for purposes of proportional representation of members of Congress, and for all federal elections.
All citiens so counted shall be alloted to cast one vote, in a manner decdied by Congress and the several states. Citizens younger than the age of eighteen or otherwise in need of a legal guardian shall have their votes cast by proxy by their legal guardian, save for those who specifically register to vote on their own.
In any case where a real citizen and that citizen's guardian both cast otherwise valid votes on the citizen's behalf, the vote of the real citizen shall be deemed valid and the guardian's proxy vote discarded.
Let's given children the vote. All children, even newborns. We value children too poorly, and parents not enough.
