HARRISBURG, Pa. -

Pennsylvania lawmakers are due to reconvene Monday after a four-week break around the primary election, and there is no shortage of ideas for plugging a potential $1 billion-plus shortfall in state revenue.

It's impossible to predict which ideas will become part of a solution.

Senate Majority Leader Dominic Pileggi says ``everything is under discussion.''

Gov. Tom Corbett has proposed a 3.7 percent spending increase in his $29.4 billion budget plan for the fiscal year starting July 1. The increase would help pay for a new public-school grants, social services and the rising cost of public-employee pensions, among other things.

Erasing the shortfall may come down to a combination of spending cuts and new taxes.
