Normally I'd write an original response but I think this post summs up what my response would be well enough:
By the way not sure more people voting neccesearly equates to being easier to rig. If only a single person voted it would be much easier to see if its rigged, just go ask the one person how they voted and you have your answer in a few seconds.. .With tens of million voting determining if the system is rigged becomes far more complicated and would require more man-hours to get to the bottom of it.
In fact even if we talk en mass, 10% voting who really care about their vote is harder to rig because they care enough to bother to double check afterwards if their vote was registered and counted and if it isnt they may make a stink about it.
If you have 90% voting with 10% really being enthusiastic and 80% being apathetic and not caring too much, then the vast majority of voters arent even going to check their vote or say anything, relying on others to detect any possible fraud.
So it would seem in this scenario even then more people voting means its harder to detect fraud, not easier.
