You have to prove it. There needs to be some way to prevent fringe candidates from perpetrating this on the process. She really should have no standing. Let Hillary do it herself if she thinks that she can overturn the results. Of course, she won’t because it makes her look like a fool.
If there was a dozen cell phone calls between Stein and Hillary, would this not constitute at least a suspicion of collusion? So what about this huge phone data collection project of the NSA? Surely these records exist somewhere. I guess I’m naive enough to think that justice will be done in 21st century America. These fools must be brought to account for this crap.
