Some of this. Also, Loeffler is cartoonishly horrifying. Maybe her cartoon villain qualities seem more offensive to some because she’s a woman, but she’s objectively more horrifying than Perdue.
Probably a little of this. There’s probably a bit of anti-Semitism baked into American politics in general, but Perdue hasn’t altered any pictures of Ossoff’s nose in months, so I guess they didn’t find it that effective.
More generally, while Ossoff is young, smart, and a good candidate, he isn’t quite as compelling as Warnock. Georgia was won with black organizers registering black voters. The senior pastor at Ebenezer Baptist and a child of the poverty resonates in a way that a child of privilege turned documentarian doesn’t. Add in Loeffler’s making this election about the black church too.
I suspect that enthusiasm was far higher for Warnock than Ossoff. I could also see some generally R leaning, white Christian values voters seeing Warnock as acceptable and then also voting for Perdue.
If you look at county by county numbers, there wasn’t that much splitting of tickets, just a little here and there, always favoring Warnock over Ossoff.
What’s absolutely amazing to me is that during the height of extreme right wing nationalist identity politics, Georgia just elected a Black senator and a Jewish senator.
