Not school choice. Children spend most of their childhood in school. Shouldn't the parent decide which school is best?
Gun run schools (you call them public schools) are hardly choice. We favor the complete separation of school and state. The purists think this should happen tomorrow morning. The practical among us see a need for vouchers for a few years to allow the private school industry to build up its capacity.
Either way, full choice on all education issues is with the parents. No more political fights about spending, curriculum, evolution/creation, phonics/whole language or whatever.
I get the feeling that conservatives think that they have to diss libertarian ideas even when they agree with conservative principles.
