The Economist describes how both

The Economist describes how both parties (but especially the Democrats) remain hopeless on the voucher issue:

It is only a small exaggeration to describe the Democratic Party as a wholly-owned subsidiary of the teachers’ unions. Throw a brick into any large gathering of Democrats and you are sure to hit a teacher or two. It is impossible to win a nomination for national office without pledging allegiance to the unions on vouchers.

This means that the job of championing vouchers falls by default to the Republicans. But Republicans are hardly the ideal champions for a measure that primarily benefits poor blacks in the inner cities — not least because their own base, the middle-class suburbs, are perfectly happy with their local schools (which are often the reason why they live where they do). Very few think “their” schools really need a large influx of poor black children using vouchers to flee from inner-city schools.

Besides, few if any Republicans are serious enough about vouchers
to increase them as Milton Friedman suggests:

Raise the voucher amount to $7,000 — the sum that Ohio state and local governments now spend per child in government schools — and make it available to all students, not simply to students from low-income families, and most private schools accepting vouchers would no longer be religious. A host of new nonprofit and for-profit schools would emerge. Voucher-bearing students would then be less dependent on low-tuition parochial schools.

So, I remain an independent.
