I mean actual technical evidence or reports to suggest that systems run by the the people running the elections ignored warnings that attacks like this usually give off, or they didn't secure their systems to prevent certificates signed by a bad CA from being trusted, or any other security mechanisms that should be in place to protect data that goes over an untrusted network? Why should I believe that the people whose job it is to secured the election systems failed at their jobs? Also, has it been confirmed that starlink was used for the voting machines to communicate to anything?
That being said, if it was my goal to cause FUD about the election results I would throw out words like homomorphic encryption or ciphertext modification attack, or chosen ciphertext attack, etc.... If you don't know what those are, look them up, and let those creative juices flow. It doesn't have to make technical sense to those who actually know how it works, but if done right it totally get a lot of people to have doubt, even the techies who aren't crypto or math nerds will be unsure.
