O'Connor and vouchers
O'Connor sided with conservatives and members of the Orthodox Jewish community, who argued in favor of permitting school vouchers and government funding for computer equipment to religious schools.
"The fact that she was a justice on the court while this evolution was going on meant it happened at a more moderate pace and more moderate tone than if you had a bloc of conservative justices," said Nathan Diament, director of the Orthodox Union's Institute for Public Affairs.
She did allow vouchers in the Zelman case, but only on a very limited basis. Her replacement could throw it wide open.
