The only time the country is united is when we are attacked from outside. Pearl Harbor and 911 come to mind. But that requires something so big and egregious that the Mainstream Media can't spin it their own way due to the extreme anger of the populace.
What could unite the people in this situation?
The fact that the election steal involved foreign countries as a major player. Of course hardcore commies won’t be united but regular Americans even those usually voting dem will be united.
