ATLANTA --- A 2.4 cents a gallon gasoline tax hike, scheduled to go into effect this week, has prompted some state officials to call for the governor to suspend the increase. Consumers are already paying a 17.7 cents a gallon gas tax. State Lt. Gov. Mark Taylor and Sec. of State Cathy Cox, who are seeking the Democratic nomination for governor, favor suspending the tax hike. Georgia Gov. Sonny Perdue, a Republican, took that step last fall to help Georgians deal with soaring gasoline prices after Hurricane Katrina, according to an Associated Press report.
