State senators are expecting to vote Friday on changes to a plan to expand alcohol sales in Pennsylvania, but they may not have the 26 GOP votes they'll need to send a bill to the House.

Senate Republicans are circulating the gist of a proposal, but Majority Leader Dominic Pileggi says it's likely to keep changing before anything is brought up on the chamber's floor.

"It's an amendment with a lot of moving parts, the underlying bill has a lot of moving parts, and we need to make sure the members are comfortable with the language of the amendment," said Pileggi, R-Delaware. "They're comfortable with the concepts, but the implementation of the concepts remains to be seen."

Tentative vote times earlier this week came and went as GOP lawmakers churned over possible tweaks to the proposal.

The plan could shut down state stores as it allows the sale of wine, spirits, and beer in more places than are legal now.
