The voucher idea is flawed.
The local communities will tailor it so that voucher eligible schools will be the same liberal garbage that has been taught there for years. Actually, the liberal nonsense grew as Federal dollars flowed in.
The truth of the matter is that the States need to take education back from the Feds as a States issue where the Fed has no standing.
The only way the States can stand is if they change the 16th amendment and have all income taxes collected by the State governor and then sent to DC. States would be allowed to withhold monies to address any unfunded mandates made by the Feds.
