Florida's school voucher program is once again in the spotlight.

Right now more than 70,000 children get vouchers to attend private school, but the sticking point now is where the money comes from to pay for those vouchers.

For Marlene Desdunes, a 500-mile trip to Tallahassee is worth it if it means saving school vouchers. Her son was one of tens of thousands of low-income children enrolled in Florida's corporate tax credit scholarship program.

"As a parent, I was not comfortable with my middle school that he would have gone to," she said. "Therefore, the tax credit scholarship program gave me a choice to enroll him into a private school where I felt he would thrive."

That program is now being challenged in court, with the Florida Education Association arguing the vouchers are unconstitutional.

It's a court battle that, in many ways, has been waged before. Nine years ago, the Florida Supreme Court struck down Florida's other voucher program, ruling that it used public money to help fund private education.

Now the question is whether tax credits amount to public money, too.

Former Gov. Jeb Bush started the program in 2001 and had it funded by private companies, so technically public money is not being spent.

But Angie Gallo with the Florida PTA said the taxes those companies don't have to pay amounts to public money being lost.

"We believe in high quality education for all children and we feel like the money shouldn't be diverted from public education, that it should stay - public dollars should stay with public education," she said.

But Desdunes said there's more value to the voucher program than money.

"The benefit is having individualized instruction," she said.

Now it's up to a judge to decide who is right. A ruling is expected within the coming weeks to determine whether the voucher program is unconstitutional.

The judge's decision doesn't particularly matter, though, because both sides have said they plan to appeal all the way to the U.S. Supreme Court if they lose.
