But surely you are not arguing that today citizenship is past only through the father? Nor when Obama was born?
What was the role of Partus Sequitur Patrem in 1960 in regards to citizenship?
Geeze, you are not getting it. No one is saying that "citizenship" is passed exclusively through the father. It WAS prior to 1922, but it is not subsequent to that act.
The Point is not that citizenship was passed through the father, the point was that "natural born citizenship" required BOTH PARENTS to be of the same allegiance. When a woman was automatically naturalized by marriage, both parents were ALWAYS Citizens. This "dual national" crap didn't occur till congress passed the Cable act in 1922, and their intentions were certainly not to change eligibility requirements for the Presidency.
What was the role of Partus Sequitur Patrem in 1960 in regards to citizenship?
None. A "citizen" can have either an American mother, or an American Father, or both. Unless they have both, they are a dual national, and therefore not a "natural citizen." They are a "Frankenstein Monster" citizen, Unknown and unforeseen by the founders, and therefore uneligible.
You want to err on the side of recklessness! The rest of us want to err on the side of caution. One only need look at the horrible mess this Foreign national president has done to see why the founders wanted no such crap in the Presidency.
