What are you talking about? There was no pollster saying Ossoff was going to win. Pretty much everywhere agreed it could go either way with the current results being on the worse side of what was within predictions.
Yup. Polls are only accurate within like +/- 11% in special house elections, and Ossoff was leading in polls by no more than 2%, and probably less. This was a tossup at its core.
"Seat that was vacated under the assumption that it was a safe Republican seat remains Republican" isn't much of a headline. It would have been nice to see a win here, but it was never really expected.
