The Oath Clause
Article VI, Clause 3 requires that all federal and state officers “shall be bound by Oath or Affirmation, to support this Constitution.” This is not ceremonial. It is a legal obligation.
What the Oath Requires
When an official takes the oath, they are swearing to uphold the Constitution as written. Not as they wish it were written. Not as their party platform dictates. The Constitution. As written. An official who enforces a law repugnant to the Constitution is not discharging their oath. They are violating it. The Supreme Court recognized this in Ex parte Young: an official who enforces an unconstitutional law is stripped of the government’s protection because the state cannot authorize conduct that violates the supreme law of the land.
Accountability
The question is not whether officials violate their oaths. Many do, routinely. The question is what we as citizens do about it. The answer begins with knowing the document. Every candidate who asks for your vote is asking you to trust that they will honor that obligation. The accountability standard is simple: say what you mean, mean what you say, and when the text of the document you swore to uphold collides with a law, choose the document.
