Though it is a bill that is presented every other year in the GA congress, the current form of the Sunday alcoholic sales bill is expected to gain the most ground ever, but still fail. This bill, along with some other previous renditions basically allows a county and/or city to let the citizens decide on afternoon Sunday sales with a vote. The most recent action is that the bill got recommitted in to the Senate 2 weeks ago, but this was after almost a full year of nothingness.
There are some big name supporters behind this bill, including a laundry list of senators and reps. Two of the biggest names are Kroger and Publix. All state breweries and wineries support the bill, of course. The convenient store chains support it, though some smaller package stores are iffy about having to produce a Sunday payroll.
There are plenty of groups highly against the freedom to allow citizens to put the issue to a vote. Already infuriated by the law changes in the last few years allowing home delivery and higher alcohol content in fermented beverages, various religious and socially conservative groups are being vocal.
The bill has a chance of reaching the governor's office. But it is expected that the governors morals and values will prevent him from allowing counties and cities to chose for themselves in a democratic fashion. In an election year dominated by national economic, war, and presidential issues, and with local water and housing issues, this bill and it's subsequent repression of democracy will be overlooked.
I don't see why they don't just challenge this law as religious establishment.
