The public schools are going to get money from these grant voucher student by student under H.R. 610.  And it is an addition to any other  money.  

Have you even read H.R. 610?  I posted the text.  

"(4) DISTRIBUTION TO SCHOOLS.—From amounts allocated under paragraph (3), each local educational agency that receives funds under such paragraph shall distribute a portion of such funds to the public schools served by the local educational agency, which amount shall— 
(A) be based on the number of eligible children enrolled in such schools and included in the count submitted under paragraph (1)(A); and
(B) be distributed in a manner that would, in the absence of such Federal funds, supplement the funds made available from non-Federal resources for the education of eligible children, and not to supplant such funds."

You either being misled, in a panic, ignorant or intentionally obtuse.
