A few things to say to the naysayers
-In their one 2018 Gubernatorial poll, they had Abrams+3 over Kemp. Granted it was Abrams: 40%, Kemp: 37% with lots of undecideds, but still.... :https://en.wikipedia.org/wiki/2018_Georgia_gubernatorial_election#Polling_4
-In their 2016 polls they consistently UNDERESTIMATED Trump, sometimes by a lot:

-Trump is favored to win in Georgia anyway. There is no realistic situation where the Dems lose competitive states like FL/NC/AZ/MI/WI/PA but get saved by winning Georgia. IMO the most likely path to a 2020 Dem win is through retaining all the Hillary states and attaining MI/WI/PA at the minimum; AZ/FL/NC are 'bonus' points, and I'd even bet on AZ voting at least two points to the right of the most D favored state of the MIWIPA trio given that Trump has won back quite a few 2016 Trump skeptical right-leaning voters.
