The election of 1800 was bitter because people had different opinions on who should have been elected. Now, people still have different opinions on who will be the president however, they are not as ferocious.
Hope this helps!
I would say a 1 because his presidency is known for a start for diplomacy with China, a slow ending of the Vietnam War, domestic acts (such as OSHA and Environmental Protection) and an era of peace with the Soviet Union (communist Russia).
