(Harrisburg) -- The state Auditor General is taking a shot at the proposal to turn state liquor sales over to the private sector. There have been a couple different estimates about how much the state could stand to make by privatizing its liquor system. Estimates range from $1 billion to $2 billion in one-time revenue. But, Auditor General Jack Wagner says those figures are pure speculation. "What is the real number? No one knows what the real number is. And that’s the point I want to make today," he says. "No one knows what that real number is." House Majority Leader Mike Turzai, sponsor of a privatization proposal, says Wagner is just kow-towing to the labor union representing liquor store employees. The legislature has a full plate for the remaining month of this year’s session. It has to settle the next decade’s district lines, both at the legislative and congressional level.  The two chambers are also negotiating a final Marcellus Shale natural gas drilling impact fee. So while the governor has said he wants the state out of the liquor business, the proposal may not be voted on until spring.
