What is the realistic likelyhood of this being mandated, given how many religious private schools there are and how much money they have to lobby with?
> What is the realistic likelyhood of this being mandated
Just under a third of Californian's aren't religious [1]. Nobody is proposing to ban religious schools.
If you can't swing it, make the choice local. Each county or whatever can vote on whether to permit religious vouchers. The Bay Area will ban it. The Central Coast won't. This remains better than the status quo.
