While school vouchers are not an ideal solution, some school choice is better than none. Remember that the government takes the money anyway. Then, it forcibly gives it state-run schools to preach a philosophy that is far more insidious than what one would find in a religous school. Also, the decision of *which* school is now made by the parents. Therefore, the philosophy imparted in schools will better reflect the philosophy of the parents.
Given the choices in our neighbourhood, we decided to send our daugther to a catholic school. Certain teachers tell the kids about God and Jesus. It's all so silly that it is almost non-issue. (Really, the challenge is not in refuting such nonsense; rather, the challenge is in having my daughter continue to respect her teacher when she talks about non-religious topics.)
One reason I would vote for Bush even if there was not "war on terror" is because he might take the country a few steps further toward increased parental choice in schooling.
