I don't either. It may be tied in the way the polling is being done which understandably makes many of us tense (me included), but I haven't been convinced it'll actually be that close on the night for quite some time. People doing these doomsday scenarios of barely ekeing out a victory with 276 EV or something are deep in their own nightmares to me.
I'm tenser than I was in '20 or '22, but a lot of that has to do with the unusual circumstances of this cycle and the heightened threat post-J6. I've suspected for some time this may look something like the midterms on the night of and we may put it away much earlier than anyone in media had expected.
I think most of that is natural tightening towards the end of a race, and not that surprising given Harris has only been in the race since the end of July. I also think the polling underreports or overweights a lot of groups on account of the assumption of Trump Magic, and early voting that is not going to happen the same way as in the middle of a pandemic.
The rest is PTSD Dems or angry Twitter leftists bedwetting over the One Weird Trick they would do with her campaign instead. Of course I can think of things I would do differently, but I see little serious change in that campaign since two months ago and it's been an insanely rushed timetable.
