From what I remember the Atrim co. Dominion machines were where vote flips happened(glitch/human error) and from my understanding the Trump team worked closely with the machine/location where the issues happened. If there are more machines there and they show similar issues then it may push for all MI Dominion machines to undergo forensic audits as well. I think the play is to cast sufficient doubt at the very least.
But the forensics wont be under oath, dispooted !!!
Just a joke my dad suggested with my interpretation. If you watch heavy metal - hand over fist you may get more context.
