First, a statistical reminder: a 1 point poll with a 5 point margin of error should be considered a tie, but that said, you’d ever-so-slightly prefer to be +1 than -1.*
According to the first poll taken after the initial special election, Jon Ossoff is leading Karen Handel 48-47. This is kind of a big deal, since there was always the possibility that Republicans would circle the wagons, and first time Dem voters who came out in the special election wouldn’t come out in the runoff. What’s more, “he’s 12 points ahead among voters who went to the polls on April 18, but did not vote in the 2014 midterms.” In other words, get the vote out like we did before and he will win. And remember to give generously.
*FWIW, based on random errors only, Ossoff has a 58% chance of really being ahead based on this poll.
