The complaints (at least from me) are not about any particular election being thrown, but about how vulnerable our vote system is.
It is entirely appropriate in a democracy to not blindly trust those who run and count elections. There are probably crooks in the system and even if there aren't oversight is appropriate.
Hacks have been demonstrated,
Crimes are being prosecuted,
... I think most people would agree this is a reasonable way for the justic system to work - since we all agree that people have a motivation to alter election results, oversight and information about the vulnerabilities, investigations and legal action against crooks is all good for our democracy.
We can do better than these machines! Optical scans should be workable, but then touch screen with a back up paper trail should be too.
I think independent polling is a good independent indicatopr of the public will in elections.
