Hispanics are overwhelmingly Catholic and want support for Catholic schools. Many of the supporters of vouchers are supporters of Church schools and of creation science. I do not support school vouchers programs in general or NCLB, Local control of school is the best.
Charter Schools are not Catholic schools, they are public schools.
I agree that there is no place for creation "science" in public science education, just as I believe that it is not a good thing for public school children to be denied information about "God's Creation". Charter schools would probably not get far introducint "creation science". A family member runs a Charter School in California and I assure you that "Creation Science" is not in the currirulumn. Grandpa is the prime mover in teaching about "God's creation", and it is sinking in, thank God. My oldest grandchild, a graduate of that school won top honors in High School and is now a student at Brown.
The politics are on the Republican side. Even my liberal wife and former teacher is coming around. She was particularly distressed that the local public schools had two budget elections, an both were turned down. The legal reaction was for the Scool Board to approve a budget that was higher than either rejected one.
