I'm familiar with Swann Marcus. I can't say whether he's right or wrong. I'm not going to go Emerson poll truthing because I just don't know enough about them.
Regardless, I think the Republicans are typically overconfident and Democrats typically dooming and neurotic, all of which I find tiresome. I think the media is capitalizing on this because they want a horserace and because some of them fundamentally disdain Democrats/want Trump back. But I do suspect we may be in for a 2022 situation overall, and I think it's gonna be a very long 12 days for everyone - not just Democrats, either. I think we may see a few more fortunes turn and twist over the next week and a half, and I think it befits all of us to get away from it for a bit and breathe as much as we can, while staying informed.
