Reasonable doubt is the aim, one result being signature check, which democrats are currently doing everything they can to not have happen, which won't match up in number or signature, won't be found because the electronic fraud machines don't keep the required logs, resulting another way the fraud votes will be discarded, from not adhering to the rules. These are just two of the ways off the top of my head, the moment they cross the barrier to do either one of those checks the democrat's goose is utterly cooked
