That is NOT how the founders imagined the process.
When Aaron Burr killed Alexander Hamilton was it business or personal?
When Brooks beat Sumner with his cane...on the floor of Congress.
Business? Or a personal grievance? I reckon arguments could go either way. But so could our most recent grievances. Politics is a VERY personal business.
We haven't reached anything like the low point of the Civil War. We haven't seen economic insecurity on the scale of the Great Depression. We haven't seen destruction comparable to the World Wars. What I see in our future is a lot of disappointment and frustration. For both parties. It's been this way since Julius Caesar was stabbed on the Senate floor and before.
Sparta had two kings...perhaps because they knew the two factions could never get along.
They defeated Athens...the first attempt at democracy.
