The center had played a key role in bringing about one of the most dramatic expansions of private-school vouchers in the country, making it possible for all Ohio families—even the richest among them—to receive public money to pay for their children’s tuition. In the mid-nineteen-nineties, Ohio became the second state to offer vouchers, but in those days they were available only in Cleveland and were billed as a way for disadvantaged children to escape struggling schools. Now the benefits extend to more than a hundred and fifty thousand students across the state, costing taxpayers nearly a billion dollars, the vast majority of which goes to the Catholic and evangelical institutions that dominate the private-school landscape there.
