Lean R (would've been Tilt R/tossup with Cagle); Safe R if it goes to a runoff
You really think Abrams has zero chance in a runoff?
I don't think it's zero, but I get why one would think that she would be a massive underdog. Look at 2008 GA-Sen. Jim Martin got 46.8% in round 1 and then lost by nearly 15 points because black turnout cratered hard.
Of course, this was back when the Atlanta suburbs were pretty decently Republican rather than purple, but rural whites were more Democratic in 2008 than now.
