It could BUT that does not change the fact that the grade given is the lawful and legitimate grade.I heard it explaned it this way:
Suppose in a class of 25 people - a test is given - and will be graded on a curve. But five people cheat - and end up getting an A - thus the 5 who should have recd an A - only got a B - and those who should have gotten a B - recd a C.
Well, the National election is the same way - by cheating in some States/commonwealths - it could have changed the outcome.
I believe that the election was stolen. But that does not make Biden (if Congress accepts the certificates) the legal and legitimate President.
