ATLANTA — Eager to get campaigning, Georgia’s lawmakers will wrap up an unusually quick legislative session Thursday, likely making decisions on whether to expand the places people can carry firearms and whether to support a medical marijuana program for the ill. Equally important are the efforts that stall during the final days, a category that appears to include plans to privatize parts of the state’s child welfare system and to pull back from national education standards. By law, the legislators in Georgia’s General Assembly meet for just 40 working days every year.
