I'll bite. I'd do it at a number of levels.So as I asked above but I'll try to make it more explicit: how in a particular state that is meant to have been subject to election fraud this election could you have committed election fraud to change the result from Trump to Biden?
1. I'd maximize the number of mail in ballots out there and maximize the amount of time that those ballots could be counted. That way I have the maximum scope both for ballot harvesting in the sense of going round old folks homes and what ever and helping people make the right choice and delivering their ballots for them. It would also give scope for collecting ballot applications that had gone astray or weren't being used and filling them in for people in the hope that they would get through.
2. I would want the maximum number of drop offs for the ballots with the minimum security on them to make it easier for the ballot harvesters.
3. I'd want to be as slack as possible with cleansing the electoral roll to make it easier for anybody who was submitting fraudulent ballots to do so.
4. I would remove, or not follow as many checks as possible that might catch fraudulent ballots. I'd drop signature checks. I'd drop confirming the details on the ballot. If these rules were still in place, I'd make it as easy as possible for people on the ground to not comply with the rules.
5. I'd create a culture where everybody in the process demonized the opposition publicly to make it harder to question what was going on. Look what happened to the postal worker when the USPI interviewed him. I would not enjoy being a lone whistle blower in a culture like that.
6. I'd try and minimize access to anybody not on my side to view the process.
7. I'd hold back as many ballots as possible until the target was known. Ideally I'd aim to be just the right side of the limit for an automatic recount, but we would be doing this live on the night so that might not be possible.
8. As a last resort, I'd hand create as many ballots as I needed against a list of people whose votes hadn't been received or discarded opposition ballots.
I'd say that the first 6 clearly go on (ignoring any claims about peoples motivation), the only question is at what level. I'm not sure that any of this needs a top down conspiracy, beyond knowing that this kind of corruption is going to go on and encouraging/facilitating it as much as possible. Whether or not any of this actually happened is another question, but it looks like this is what the various witnesses are claiming. I don't think any of it requires the Biden campaign, or the DNC to directly organize.
What would you see if this kind of thing was going on? There would be instances where individual people, or a small group of people were caught committing fraud, but none of it individually would be big enough to change the result.
