most of the disputes were about the makeup and election of the senate. other disagreements concerned how "proportional representation" was to be defined (whether to include slaves or other property). they needed to decide whether to divide the executive power between three persons or invest the power into a single president. they also had to work out how to elect the president, how long his term was to be and whether he could stand for reelection. there were issues over what offenses should be impeachable. most of the time during the convention was spent on deciding these issues, while the powers of legislature, executive, and judiciary were not heavily disputed. once the convention began, the delegates first agreed on the principles of the convention, then they agreed on madison's virginia plan and began to modify it. a committee of detail assembled during the july 4 recess and produced a rough draft. most of this rough draft remained in place, and can be found in the final version of the constitution. after the final issues were resolved, the committee on style produced the final version, and it was voted on and sent to the states.
