There have been over
1,000 cases of voter fraud in just Georgia alone for the 2020 election cycle. There is also an investigation into at least one well-funded group which was instructing several thousand college students to illegally change their voter registration to that state.
And since Georgia, like most states, has no real process for verifying ballots (it is actually
illegal to verify the signature on a ballot against the voter registration card), the only reason these 1,000 people were caught was that they were actually stupid enough to use their own name twice.
In a free state, all people have a right to their day in court. Would you like a list of all the Democrats who have gone to court over election-related matters? I'm not sure if this forum software can handle a post that long, but if you wish, I will try.
