14th Amendment Section 3
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.

Seems pretty cut and dry to me. It's preposterous to allow that traitorous criminal to run for any office. While it may cause individuals to rise up in rebellion again, for which they would pay a heavy price, the damage would be much worse should he get into office.
