Likely isn't going to matter much anyway.  The dolts who throw their kids in schools expecting the schools to do the parenting and ensure the kids get good grades won't benefit whether it's a public school or a private one.  The ones it will hurt are those who actually want to succeed but won't be able to afford a good education using more of the private system.  But, the Christian right knows Jesus doesn't care about those people...only the ones with money.
