None of the voting machines used in Madison County are connected to wi-fi or the internet. All ballots are paper hard copy and under continuous lock and key. Aside from an armed insurgency (the Proud Boys?), I don't see how any fraud could occur at any of our county's polls. Granted, I'm unsure what happens when each machine's thumb drive is delivered to the court house after the polls close, but if security is as tight there as it is at the polls, we have nothing to fear.
So I urge everyone to vote this November 3rd!
