This one wasn't hard at all, yet millions were spent adjudicating it. Ridiculous. If the writers of the 14th wanted Section 3 of the Ammendment to apply to the President or Vice President, then it would have said:
"No person shall be President or Vice President, or 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 President or Vice President, or 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."
Even a sixth grader could figure that out.
This whole thing was a waste of time and money.
