According to The Constitution (last time I checked, still 'the law of the land'), as a Knight Commander, Order of the British Empire (KBE), Rudy Giuliani is forbidden to be President per Article 1, Section 9, Clause 8:
"No Title of Nobility shall be granted by the United States: And no person holding any office of profit or trust under them, shall, without the consent of the Congress, accept of any present, emolument, office, or title, of any kind whatever, from any King, Prince or foreign State."
Not that I think he has any chance of being elected, but by law he should not be allowed to be part of the election process in the first place.
Get him out of the election.
