1. A US Supreme Court Justice dies and a replacement is not confirmed before November.

2. A few US states like Florida have a sizable number of elderly registered voters die before November.

3. A state actor is motivated to tamper with voting machine software in a way that is:

- Obvious to Democrats who are biased to believe that Russia wants to help Trump win.

- Invisible to Republicans who are biased to believe this "hacking" is a hoax by Democrats.

In a world of "filter-bubbles" and with current vulnerabilities of vote-counting software[1], can we design a system which can prevent a division in belief in the legitimacy of the 2020 election?
