This sort of problem seems to be very USA-centric.
Here in Oz, we have the AEC (Australian Electoral Commission) whose sole purpose in life is to run elections (local, state or federal). And while a lot a mud has been slung at various politicians and parties for trying to rig the election (generally the old "cemetery vote" scheme), not one of them has ever been proven and NO-ONE HAS COMPLAINED ABOUT THE AEC (*). The average Australian's trust over the AEC's impartiality is rock-solid.
Which is one of the reason why there's such a brouhaha over the fact that the "Marriage Equality" question is being handled by the ABS (Australian Bureau of Statistics, which lost all public credibility recently) rather than the AEC.
(*) The exception is the odd political party complaining they are not on the ballot even though they never supplied the requisite number of signature. C'mon people, if the "Party party party Party" can get on the ballot, do you *really* think your inability to get on it is because the AEC "hates you"?
