Also Strange how Ossoff is underperforming Biden
Perdue probably outperforms Trump. He is less divisive and thus will probably do better in the Atlanta suburbs.
People make jokes about it all the time but the fact is that Johnny Isakson far outperformed Trump in 2016 precisely because he did way better in the suburbs. Given Perdue's genericness, it's not hard to imagine him also doing so, though definitely not to the same degree.
Several Republican Senators outran Trump in 2016. Ron Johnson outran him a lot in WI and even Toomey & Burr did.
I expect the same happening in GA and NC. We have several Polls now showing Trump and Biden within two Points of each other. NC is very polarized. Very few Indies there. Tillis could barely hang on here.
