This is pretty complicated, so here is some clarification on this referendum for those who are interested:
-It's a "transportation" referendum, so it's not just transit. It includes road expansions and even some money for an airport control tower.
-The Atlanta region as a whole (10 counties) will vote on July 31st.
-In order to pass, the referendum must have an overall yes vote across the 10 county region. So several counties could vote against it and it could still pass. What matters is only if the overall yes vote total passes 50%.
-The referendum would start a 1% sales tax that would last for a maximum of 10 years. If the total amount needed is raised early, the tax would expire early.
-The total amount to be raised is $7.2 billion.
-85% of the money ($6.14 billion) goes to construct "regional projects." The money would pay for these projects only.
-The list of regional projects is set in stone and was developed and approved unanimously by elected officials from across the region.
-The full projects list is avialable here:

-The remaining 15% (a little more than $1 billion) is divided among local jurisdictions (each county and city in the region). The amount for each jurisdiction is determined by a formula based on the number of people and road lane miles. They can use this money on any local projects they want.
-Local jurisdictions are not required to announce before the vote what they will spend their 15% on. So far Cobb County and the city of Atlanta have both released a local list anyway.
-Support for the referendum has come from all sides. The business/corporate community is leading a well-funded support campaign. Politicians ranging from the republican Governor of Georgia to the democratic mayor of Atlanta have voiced strong support. The local Universities (Emory, Georgia Tech, Morehouse, etc) are all in support. Most local transit/sustainability non-profits are all in support. MARTA supports. The Beltline supports. Local unions are in support.
-Opposition for the referendum has also come from all sides. Tea Party groups and some suburban/exurban officials oppose the tax simply because it is a tax. Some oppose because they don't support transit expansion. Some don't believe there is a traffic problem in the first place. The Sierra Club of Georgia opposes because they think there is too much road expansion on the list. The Dekalb County NAACP opposes because they think the project list ignores heavily African American south Dekalb County.
-Polling has been limited and is mixed. One poll showed the tax barely losing, while another showed it winning. In general there is strong support from the urban core (Fulton County, Dekalb County, Clayton County, City of Atlanta, City of Decatur), moderate support from urban nodes in suburban counties, and moderate to strong opposition from suburban/exurban counties.
