A lot.
From the Office of State Budget and Management:

The calculations presented in this report assume that at least 50% of the new recipients of the extended voucher scheme will have previously been in a public school.
What many people do not notice is that when money leaves a local school system because of a voucher, the same number of buildings still need to be maintained and powered, buses gassed and kept in working order, and facilities sustained. If ten percent of students left a school, they do not take with them the responsibility to heat/cool the classroom space they would have personally had or the electricity that powered spaces.
A bus that previously carried 45 students to school and now carries 35 still has to travel the same number of miles.
Some counties are slated to lose as much as 8% of their state funding and we have candidates for both state super and governor who want to cut federal funding for our schools which sits at about 12% of our total public school funding.
That could cripple school systems that already are underfunded.
Just look at the LEANDRO decision.
