Voted for Cagle. He's pretty bland and kind of a block-head, but he does best against the Stacies in polls and is the only Republican with even the slightest change of hitting 50% tonight, foregoing a runoff that would give the Democratic opponent an advantage.
To be fair, I don't think pollsters ever polled the Stacies vs another opponent. I've only seen Stacey vs Cagle.
There was a poll done with all candidates back in late February and Casey did the best of all candidates and Hill did worst. Obviously since the poll was that long ago, name recognition was a big factor, but it's all I have to go by. The other Reps, even at this point, with the exception of Brian Kemp, are still relatively unknown, and I think the GOP needs a known name to take on the "rising star" Abrams.
