I suspect the next elections may be dramatic in some places.
For example, in many areas, the Democrats will find it extremely hard to vote the dead and the institutionalized incompetent. But in very Democrat districts, they will, anyway.
So if Republicans send poll watchers to these Democrat districts, there are going to be some serious brawls. “So how come this poll provided 2000 ballots thought only 300 people entered and left the building during that time?”
Sadly you are right. And as long as those in charge don't do anything to stop the cheating, the "serious brawls" could trigger Civil War II. Phony elections have been the trigger point for civil unrest and wars in many nations down through the years. Once a sizable percentage of the population loses faith in the integrity of the electoral process, it is left with no peaceable means to alter its plight.
