Poll has blacks at 26% of the electorate with Nunn at 29% with whites. Even in 2010, blacks made up 28% of the electorate. Given the early voting numbers, they will make up 30% of the electorate tomorrow. So according to this poll, Nunn is favored to win outright, which is glorious news!
Let's hope you are right and she wins outright tomorrow. Otherwise, it's going to be tough--I think her only chance of winning in the runoff (which I believe is likely) will happen if the GOP can assure the 51 majority (either tomorrow night or after the Louisiana runoff). And even then it will be difficult.
She has run a great race (as has Carter)--and I did not expect either of them to be in the game this late in the contest.
