Tom Corbett's proposed cuts to the education budget in Philadelphia. Like many other cash-strapped urban districts, Philadelphia is trying desperately to emerge from a quagmire of red ink and underachievement. A state takeover in 2002 did little to eradicate the financial, academic and violence problems that have plagued the schools for years. (AP Photo/Alex Brandon, FILE)
