Although I have no great attraction to Trump (other than he's not Hillary) I voted for him.
So, as an IT consultant I'm just being honest - It is entirely possible for a voting machine to be "hacked" in both the standard and non-standard definitions of being open to a "hack".
The machines would have to be connected to the internet directly (those with electronic monitors and drivers) or indirectly (with email or batch processing files as input).
Also I can guarantee that there are MANY engineers out in hyperspace land who could connect even an older machine to the internet and do it in an hour or two, at least the hardware aspect - then another effort by a software engineer to get it to work on the hardware.
The point is that a project would have to be launched to examine every voting machine in every precinct in every state to FIRST of all calculate the percentage of existing voting machines which are hackable via a direct or indirect connection to the internet. A colossal undertaking and that is just the beginning of a study to determine if the Russians are involved.
In addition all machines would have to be locked down to prevent falsifying the evidence connected to the voting machines themselves.
IMO, it is
very unlikely but it has to be demonstrated with facts not wild unprofessional speculation (of course my speculation is neither wild nor unprofessional
).
And certainly there could not be an overturn of the election without this kind of a protracted IT project being launched.
There is absolutely no way that it could be determined if Russia's interference was involved via the IT arts and sciences even if someone came forth with a verbal "confession". Evidence, evidence, evidence.
Now if they came forth with evidence (real not imagined or falsified) that would be different.
