Electors cast separate ballots for President and Vice President.

Fairness has no single number, so Constilumen doesn’t invent one. Instead it traces two things the record can show precisely: which barriers to voting the Constitution removed, and how the promise of equal protection was read, narrowed and widened over time.
The original Constitution left voting qualifications largely to the states. These amendments took specific grounds for denying the vote off the table nationwide.
An amendment states a guarantee. Whether it was honored in practice is a separate question, and the decisions and laws below show how long some took to enforce.
Amendments, decisions and laws about who votes, how districts are drawn and how elections are decided.
