HARRISBURG — Plans collapsed Thursday for a vote in the state House of Representatives on a bill to expand legalized casino gambling in Pennsylvania and deliver more tax revenue to the cash-strapped state.

With legislative approval of more than $700 million for several universities tied to passage of the bill, partisan finger-pointing erupted.

Meanwhile, the state's largest university, Penn State, warned that school operations were already suffering as a result of the holdup.

House Democrats, who control the chamber, gave conflicting reasons for the postponement, but said they expect to be back Monday to work anew toward passage of the bill to legalize table games at slot-machine casinos.

House Republicans largely oppose the measure.

In a late-night session Wednesday, both sides spent nearly five hours debating university funding, floor procedure and gambling-control regulations before they turned to accusing each other of playing dirty tricks.

Legalizing table games was a key element of October's state budget agreement, which wiped out a multibillion-dollar, recession-driven shortfall by raising taxes, tapping reserves and cutting spending.

Adding games such as poker, blackjack and craps to the state's slot-machine casinos was supposed to provide $320 million over two years to help cover more than $700 million this year in discretionary spending for Penn State, Temple, Pitt, Penn and Lincoln.

Without the table games revenue and with tax collections lagging projections, the university subsidies would tear a hole in the state budget, Gov. Ed Rendell and other Democrats argue.
