For the life of me I don't understand why there aren't thousands of humans chimping out in the streets. It's to the point where for blue collar workers it's pay the rent/mortgage and starve or be homeless and eat.

So, they're worried that they won't be able to cheat fast enough to win this time?

I would imagine that they are worried that the populace at large will realize the game is rigged since so many will have decided to abandon what they thought they knew. That and so many liberal-base people will have expired thanks to their medical experimentation at large. The publicizing of their fears serves two purposes: when they rig and if it is successful, they can claim another movement of the people since so many were 'afraid' of a loss. On the contrary, it also provides an excuse as to why they lost, if they end up not being able to rig past perception, or perhaps setup the stage for a later "we didn't rig it, they did".

Biden, 81, insists that he is the best person to take on Trump and is hoping that improving faking economic data, pushing abortion and infrastructure collapse will help him win 

Hopefully, but doubtfully; Americans understand that 'cost of living crisis' is caused by Democrat policies. It is not specific to Joe Blow Biden.
