Under both bills, voters in each county would have to approve any transit sales taxes.
As the AJC recently reported, Cobb County's ambivalence to joining a regional transit system has complicated lawmakers' efforts to hash out the details of an expansion. Deal said each county and its taxpayers must decide whether they want to embrace a regional system. But he cited "an evolving attitude" about transit by some counties, which he called "a good thing."
"Cobb and Gwinnett, I think, are the two most likely candidates for addition and expansion of a rapid transit system," Deal said. "But, there again, that's going to come down to the politics of those counties and the wishes of the voters of those counties."
