It has only been 56 years. As Americans, we are pleased to call ourselves one of the world’s oldest democracies. We are actually one of the world’s newest. Democracy, after all, is government shaped by the will of the people. But until 1920, roughly half the people were not allowed to vote, disqualified by dint of gender. And until 1965 — 56 years ago — roughly 10 percent were restricted by color of skin.
