Dance of Democracy was established to teach the principles and promote the activities of citizenship, the speech and the engagement, that cultivate empathy and understanding on both sides of the important issues of the day.
The most potent checks in the Constitution are created to check the legislative power. This is because the assignment of power to the legislature is broad and includes the most difficult and sensitive mission - to plan for the future, an unknown. The single most powerful check in the Constitution is the creation in Article One of two entirely separate debating houses (a House and a Senate) which must come to complete agreement before legislation can become new law. This powerful check is fortified by an executive veto and judicial review.
This most well-known balance, Balance of Powers, begins by distinguishing the legislative branch in Article One to perform the central democratic processes of participation and engagement. The entire body politic are to be engaged in this "political" branch, debating, considering, and even speculating, how law may be adjusted to further the common good for the future. Meanwhile, the balance of powers assigns to the other domains in government (the executive and judiciary), in Articles Two and Three, the power always to act in the present to enforce and implement existing laws to protect the body politic and its citizens.
The challenge of the Framers in making a constitution was to establish a government that would be both limited and robust, a government with the power to protect the body politic, without becoming a tyranny. This limited and robust government is the miracle the Founders wanted to establish.
