The trouble here is that the election fraud gave them the power, and they can block any effort to rein in the fraud.
Unfortunately, all the other crap out there has served as a very useful (to the left) distraction from that critical issue.
It is the same with many other issues. Ill informed people get online and pontificate before they've learned what they are talking about.
But I think there was election fraud through the machines too, but I think the dominant method of election fraud was fake ballots and "ballot harvesting", such as has taken place in nursing homes. OilPainter has given an example of one such incident.
The nursing homes are just begging for it. The other thing about mail-in votes is that it enables vote-buying and voter intimidation, which were the reasons we went to the Australian ballot/secret ballot in the first place.
