While that PPP poll did correctly put the GOP candidates for Governor and Senator ahead, they were a bit more favorable to Democrats. Purdue won by 7.9% while the poll gave him 2%. The Gubernatorial race was won by Deal with 8% while this poll gave him 5% (while hitting 50%). The Gubernatorial one was within the MoE while the Senate race was 2.6% off the MoE. That being said, even if we say that the Georgia electorate will be as red as it was in 2014 for the 2016 elections, Clinton would (after "adjusting" the PPP numbers to match the actual result) narrowly beat Cruz in Georgia while losing in single digits to Christie, Bush, Paul, and Huckabee. The best of the group would be Bush winning by 6.9%. The worst of the victorious GOP group would be Paul and Huckabee who would win by 2.9%.
While those numbers represent only one poll from last fall and from a more red electorate than we will likely see in 2016: this analysis does help to put the limited data that we have into perspective.
If we use the Cook PVI off of the most recent poll (CNN/ORC released the 2nd of June), in Georgia:
Clinton v Bush: Clinton +2
Clinton v Cruz: Clinton +3
Clinton v Paul: Paul +5
Clinton v Rubio: Rubio +3
Clinton v Walker: Walker +3
An ABC poll conducted over roughly the same time frame only tested Bush but got better numbers for the GOP. Extrapolating that would give us:\
Clinton v Bush: Bush +3
Just before that, Quinnipiac released a more comprehensive poll that if we extrapolate the same way:
Clinton v Bush: Clinton +4
Clinton v Christie: Clinton +3
Clinton v Cruz: Clinton +5
Clinton v Huckabee: Clinton +1
Clinton v Paul: Paul +2
Clinton v Rubio: Rubio +2
Clinton v Walker: Clinton +2
Clinton v Trump: Clinton +12
All in all, these three polls along side the PPP polling from last cycle show that this race will be far from a lock to stay red in 2016. That being said, team red is still a favorite here outside of a Cruz or Trump nomination.
Senate: This one still looks like a very likley GOP hold regardless of how the Presidential race here turns out. Johnny Isakson, despite his health issue, will likley be back in the Senate in 2017. The best chance the Democrats would have had here would have been if Michelle Nunn, Jason Carter or former Governor Roy Barnes decided to run. They have all declined along with Atlanta Mayor Kasim Reed.
The most likely Democratic candidates:
Valarie Wilson - Former President of the Georgia school boards association
Stacey Abrams- Minority leader in Georgia House
John Barrow- Former US Rep.
Jim Marshall- Former US Rep.
