Neither Maryland nor New Jersey has a Blaine Amendment. However, California, Illinois, and Florida do. Back when I was a high school student in Maryland in the 1970s there was a big push, led by the Catholic church, to get direct state aid to religious schools. It never went anywhere.
There was an attempt in 1967 to repeal New York’s Blaine Amendment; I think it got 29% of the vote in the required referendum. There has been AFAIK no real attempt since then. Most voucher referenda have lost by similarly landslike margins everywhere they have gone before the voters in the US, not a single one has passed.
