America already made daylight saving time permanent once. In December 1973, 79% of Americans supported it and Nixon signed it into law. By February 1974, eight weeks into the experiment, support had collapsed to 42%. The policy never changed. Winter arrived. Sunrise in Washington DC came at 8:27am. Kids left for school in total darkness, carrying flashlights and wearing reflective tape. When Congress moved to repeal, members cited the deaths of eight Florida schoolchildren in the first weeks of the change. The energy case collapsed too. The whole point was the oil embargo, and the Department of Transportation concluded the fuel savings were too small to matter. Ten months after signing it, Congress repealed it and Ford put the country back on standard time. There's a mechanism that makes this cycle repeat: permanent DST is only ever voted on when the sun is up. Polls run in the abstract, votes happen in warm months, and the benefit, a free hour of evening light, is easy to imagine year-round. The cost is concentrated in about 10 weeks of dark winter mornings and only becomes real after implementation. So the policy polls beautifully right up until January. Today's vote happened in July. The 1974 law passed in December, right before the exact winter that killed it. If this clears the Senate, the first real test arrives in January 2027, when sunrise in Indianapolis comes after 9am. Sleep researchers have watched this loop for 50 years, which is why the American Academy of Sleep Medicine, the AMA, and the National Sleep Foundation all back the opposite reform, permanent standard time. Congress just picked the one version of clock reform America has already tried, hated, and repealed.
