The district court ruled that the 14th amendment, Section 3 does not apply to presidents. The colorado supreme court overruled them and said that it does.
This is why the 14th amendment does not apply to presidents. If you read it it lists electors, people that have taken an oath of congress, officer of the US or member of state legislature, executive or judicial officer of any State, to support the US. It does not list the president or vice president in that list. So why would it apply to them? Here is the text:
No person shall be a Senator or Representative in Congress, or elector of President and Vice-President, or hold any office, civil or military, under the United States, or under any State, who, having previously taken an oath, as a member of Congress, or as an officer of the United States, or as a member of any State legislature, or as an executive or judicial officer of any State, to support the Constitution of the United States, shall have engaged in insurrection or rebellion against the same, or given aid or comfort to the enemies thereof. But Congress may by a vote of two-thirds of each House, remove such disability.
Show me where this applies to presidents.
