Every fall, Americans are plunged into darkness an hour earlier when the clocks turn back at the end of daylight saving time. Many see the beginning of standard time as a mild annoyance. Sun lovers view it as the unfortunate start to a season of afternoon sunsets. Parents, as I can now attest, experience it as sleep-wrecking proof that the human construct of time is no match for the anarchy of toddlerdom. But I am convinced that our annual “fall back” is something worse than all of these things: not just an inconvenience, but an act of state-sponsored voter suppression.
