The chances of success for legislation letting voters legalize Sunday alcohol sales at stores got a lot better Wednesday when it easily zipped through a Senate committee. In a dramatic contrast to past years, no one spoke out against the bill when it came before the Senate State and Local Governmental Operations Committee on Wednesday, and it passed on a 6-1 vote about 40 minutes after the meeting began. Senate Rules Chairman Don Balfour, R-Snellville, a co-sponsor of the measure, said it could be on the Senate floor for a first-ever chamber vote by the middle of next week.
