Just as a hypothetical Ben, but if an election were to be thrown via voting fraud (as has happened countless times, in countless countries), why would anyone accept the results as legitimate?  Would you as a candidate?

I am not saying that our voting process is necessarily significantly corrupt or manipulated --- I suspect that it is not.  But it is the ELECTORAL PROCESS, that which we are currently in the midst of, that is most certainly rigged and corrupted in favor of the pro-Establishment candidate by Establishment forces and powers.  I believe that it is THAT which Donald Trump is trying to say (but failing to make clear) is what is "rigged", NOT the voting itself.
