SEPTA funding hitting a road bump?

Two US legislators from rural areas of Pennsylvania, oblivious to the fact that cities subsidize their entire way of life (see here), have taken issue with the idea that the state should help fund Philadelphia's transit system and thrown a wrench into the approved plan: they attached an amendment to federal legislation to prevent the addition of tolls to I-80, the critical component that allowed this deal to pass. Thus the fight must now move to the US Senate, as though state politics weren't obtuse enough... Rendell has also countered by resurrecting his intent to lease the turnpike instead, yay; more of his justifiable crankiness here. Sigh.
