Like many observers, I usually read reports about political goings-on with a sort of weary cynicism. Every once in a while, however, politicians do something so wrong, substantively and morally, that cynicism just won’t cut it; it’s time to get really angry instead. So it is with the ugly, destructive war against food stamps.

The food stamp program — which these days actually uses debit cards, and is officially known as the Supplemental Nutrition Assistance Program — tries to provide modest but crucial aid to families in need. And the evidence is crystal clear both that the overwhelming majority of food stamp recipients really need the help, and that the program is highly successful at reducing “food insecurity,” in which families go hungry at least some of the time.

Food stamps have played an especially useful — indeed, almost heroic — role in recent years. In fact, they have done triple duty.

First, as millions of workers lost their jobs through no fault of their own, many families turned to food stamps to help them get by — and while food aid is no substitute for a good job, it did significantly mitigate their misery. Food stamps were especially helpful to children who would otherwise be living in extreme poverty, defined as an income less than half the official poverty line.
