Ted's got the NBC question hanging over his head. Unless that's resolved by no less than the Supreme Court, he's getting nowhere close to the Oval Office. Not even as VP, who must also be eligible.
I don’t think we need the Supremes. It’s pretty much spelled out here, isn’t it?:

“In a general, a Child Born Outside the U.S. is a Citizen at Birth when the Childâs Parents Are Married to each other at the Time of Birth
IF...”One parent is a U.S. citizen at the time of birth and the birthdate is on or after November 14, 1986
AND... “The U.S. citizen parent had been physically present in the U.S. or its territories for a period of at least five years at some time in his or her life prior to the birth”
(This INS pages seems to say that the birthdate of the child can be before 1986 only if the mother is “not married”.)
Another scenario:
A Child Born Outside the U.S. is a Citizen after Birth
IF⦔The child was under 18 from December 24, 1952 to February 26, 2001”
AND...”The child was residing as a Green Card holder in the U.S. and both parents naturalized before the childâs 18th birthday”
