The absurdity of holding in-person primary voting during what is rapidly evolving toward a national quarantine is self-evident. What’s not as obvious is that in-person voting in general is an indefensible anachronism, that survives partially out of inertia and traditionalism, but mainly because it’s an extremely effective voter suppression mechanism.
Voting in person makes no more sense than filing your taxes in person. Mail-in systems, such as that used in Colorado, work perfectly well. The coronavirus epidemic merely puts an exclamation mark on how important it is to reform our voting practices immediately.
