Trust is more than putting your faith in things a company doing your internet voting can generally control such as system competence and staff behavior.  A larger fear and one that seems to me is growing by the day is (i) internet hacking and (ii) unforeseen system failures caused by someone else. 

I doubt some Russian hacker has MK Elections on their target map.  But a hack into a larger system that MK Elections relies on could cause chaos to MK systems at the time OPA is conducting its election.  The larger risk are system failures further up the food chain.  One month ago, the largest IT outage in history was triggered by a botched software update from internet security giant CrowdStrike.  Thousands of companies, large and small, didn't know what him them.  All they got was the blue screen of death on their computer......... some for days.  All of OPA Board and Election Committee faith and trust in MK Elections won't help in such situations.

There are a lot of bad actors out there, state-sponsored and private.  Both are growing.  This is why we don't do internet voting in local, state and federal elections.  Unfortunately, these risks have to be considered for HOAs who choose to include internet voting component.

Anyway, food for thought.
