OATH of OFFICE
The oath of office required by the sixth article of the Constitution of the United States, and as provided by section 2 of the act of May 13, 1884 (23 Stat. 22), to be administered to Members, Resident Commissioner, and Delegates of the House of Representatives, the text of which is carried in 5 U.S.C. 3331:
I, AB, 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 faithfully discharge the duties of the office on which I am about to enter. So help me God.

If the guy wins, he may have to "revise and extend" his remarks on revolution before he takes that oath.
