the Rubio camp DOES know he isn’t eligible as i spent 15 minutes on the phone talking with a staffer explaining, in excruciatingly plain language, that anyone having one or more foreign citizen parents at birth is a citizen... but CANNOT be a natural born citizen as they can also be a citizen of another country
the term, natural born citizen, means someone is a citizen NATURALLY ... as there are no alternatives.
this is a very simple concept ... that has been in use since long before the founders used it in the Constitution
additionally, the Rubio camp could reject any such offer... and follow it up with a ‘teachable’ moment to explain on a national stage the simplistic reason why he cannot accept any such honor
in so doing, he would show that upholding the Constitution (ie: the foundation of all law in the US) is the utmost priority in a nation of laws
By your definition Thomas Jefferson was not eligible to be President. Neither was Madison, Jackson, possibly Van Buren...
