Because the DPA starts with a divorce. Unity requires marriages.

To use Carl's analogy, think of us as a Football team. Our President is the Coach. The running back might have one idea on how to advance the ball, the wide receiver thinks he's open, one of the guys on the bench has seen this before and think he knows best ... they have conflicting opinions on how to advance the ball. But, the wining team executes the same play and works in a coordinated fashion.

It does not matter that there are different opinions, on the playing field they agree to function as a team.
