I don't know why this is such an issue for you.  Churches have been getting tax breaks or decades, with the stipulation they stay our of politics. Religious leaders and some members of Congress have been pushing to remove the wall between church and state.  Churches will benefit greatly from tax money routed to them through the voucher program.  Where do you think that money will come from?  Public schools will be impoverished and may close.  That may sound great to you; do you like the idea of ALL available schools being private?  I know some charter schools which will love it; the only reason they are constrained from teaching history as bible stories is the tax money they get now.
