Corbett has been pursuing an education policy that is diametrically opposed to the Pennsylvania Constitution. Rather than providing for the maintenance and support of public schools, the governor has embarked on a crusade to destroy them by sharply cutting their funding while enacting programs to benefit not-public schools, especially religious, or sectarian, ones. The legislation he signed at the end of last month to expand a tax-credit program that uses a sneaky mechanism to steer hundreds of millions of dollars from the state coffers into religious schools -- backed by extensive lobbying from the Philadelphia Archdiocese, among others -- is highly questionable; meanwhile, Corbett continues to push for vouchers, which are clearly unconstitutional.
