More than 50 House Democrats have signed on to a plan to spike all constitutional amendments unless the House allows voters to decide whether school vouchers will be legalized.

After hours of debate — and years of pushing from Gov. Greg Abbott — the Texas House approved a bill to create an Education Savings Account plan. The school voucher program would allow parents to use public funds toward private school costs.

The Texas House early Thursday passed a school choice measure that would allow lower-income families to use tax dollars to send their children to private school.
