Is there still a mathematical pathway for Ossoff to win GA without a runoff?
Yes. NYT currently showing 4,791,239 votes counted, and estimating 93% counted. That means estimated total is 4,791,239/93%=5,151,869, and majority is 2,575,935. Estimated remaining is 5,159,869*7%=360,630. Ossoff is at 2,266,043 and therefore could win outright with 309,892 of the estimated 360,630 votes. That's nearly 86% of the estimated remaining vote, so while mathematically possible I think we can put that possibility to bed.
