I find that hard to believe. Only "official" parties have standing?
That certainly suggests several avenues of attack. As a group, honest legal voters far outnumber all other groups combined!
And they are certainly the most clearly injured.
The “justice” system is so corrupt that I doubt it would agree that voters have standing to sue over vote fraud.
Most likely, the courts would hold that only candidates with “real” chance of winning have standing, i.e. Democrats and ‘Pubbies, have standing. The candidate would have to show that vote fraud caused him to lose the election. I think it is really that bad now.
And ‘Pubbies can’t sue or investigate vote fraud, while Democrats encourage it.
