Environmentalists say the motive for the 2004 donation doesn't matter so much as the impact: Pennsylvania's Republican-dominated statehouse is now headed by a governor so tight with the natural-gas industry that he continues to resist levies on drilling - saying yesterday that he would veto even a modest fee plan on wells that was postponed last night in the state House. Rather than tax drillers like Chesapeake, Corbett is instead poised to sign a budget that slashes $270 million for Philadelphia schools and deeply cuts social programs such as job training and aid for day care.
