I'm not for or against, but the prevailing view is that the teachers' unions are against school vouchers.  It would mean a loss of jobs to private for profit schools.  And yes, the Republicans are being insidious, because they want money to go to parochial schools and for profit schools.

The teachers' unions typically support Democrats, so anything that hurts a key ally is always good for Republicans.

Money isn't the problem.  In fact, money might be the problem in a different way.  There are 10s of countries that have better schools and cost 1/10th of American schools.  The Federal govt has been throwing money at education without achieving better results.

It's the home life and the social environment.  If kids spend their free time playing video games, watching TV, playing sports, hanging out at the wall, is it any wonder they are doing poorly.

A good education starts at home with a stable home environment and parents that care about their children's performance.  If a parent is too busy working to check on their kids, the kids on average are not going to do as well.  That's common sense.  If the parent doesn't see the benefit of school, why would the child?

My students study 3-4 hours a day at home and attend 3 after school training classes each week in math, English and literature.  That is the norm for them.  They hate it, but they get good grades.

Don't waste your vote, vote Green or Independent in the next election.
