They really dont have much choice. Their options are even more limited than in 2020, before many independents knew what a Biden Presidency would be like.
Nothing else is working. lawfare, Israel, Ukraine, giving away trillions in debt forgiveness. nothing
The biggest problem is that Trump never outpolled Biden a single time nationally in 2020 yet it was supposedly a super close race. Now he is outpolling him NATIONALLY by 5-6 points and by some 10-12 points. That means if there was a truly fair election today Trump would crush Biden in a landslide bigger than Reagan won. That clearly cannot be allowed to happen. But how to stop it?
I think there will be a black swan event to try to get people to rally around Biden and dems, or barring that, to swing the polls enough for a minute to at least make the steal plausible. You cannot "squeak it out" when Trump is ahead by 8 points the day before the election. Nobody will buy that. Has to be something to shift the polls closer to something they can accept.
Thats really a scary situation.
