Here is my understanding of the school finance proposal. As of this writing, the deal is not done. It will take $4B to fund the foundation school program. The plan is to  provide $2 billion in proration ($1B per year) and $2B  in target revenue reductions. The runs would use the Shapiro plan. What Governor Perry does not want (on the off chance that he isn’t president) is for the state to owe a bunch of money when the Legislature comes back into session.
