I'd agree with that. But in my mind, having looked at the process, I'm thinking on what basis would you claim fraud after the process. So I'm thinking it through. If someone says, hey the vote in Georgia is a fraud they'd need to give a just cause. Then the next question would be, ok so why didn't you challenge it at the time that you witnessed it.
If they challenged it at the time, it would be dealt with at the time. And if you didn't at the time, why not?
I'm not knocking the idea of calling out a voter fraud, just thinking through on what grounds you could do it after the event rather than during it.
