I’m not an American but I would argue that Biden’s resignation was in part due to people threatening to not vote. This wasn’t a move to the left but organized threats of not voting can make a difference.
Personally, I would vote for the lesser evil unless there was some kind of organized movement. Where I live, we have more than 2 evils to choose from and I choose the smallest of them.
So a minority of 27% is desperate enough to offer territorial concessions but I doubt even they are willing to give as much as Putin demands
