the Constitution, not the people

Our elected officials are to uphold the constitution, they don't have another purpose.

President of the United States (Executive Branch)

I do solemnly swear (or affirm) that I will faithfully execute the office of President of the United States, and will to the best of my ability, preserve, protect and defend the Constitution of the United States

Members of Congress (Legislative Branch)

At the start of each new Congress, in January of every odd-numbered year, the entire House of Representatives and one-third of the Senate takes an oath of office. The Speaker of the House will direct the Members to rise and the oath is administered. The original oath was as follows: "I do solemnly swear (or affirm) that I will support the Constitution of the United States."

The oath was revised during the Civil War, when members of Congress were concerned about traitors. The current oath is as follows:

"I do solemnly swear (or affirm) that I will support and defend the Constitution of the United States against all enemies, foreign and domestic; that I will bear true faith and allegiance to the same; that I take this obligation freely, without any mental reservation or purpose of evasion; and that I will well and faithfully discharge the duties of the office on which I am about to enter: So help me God."
