Not sure about the two veeps, but Chester Arthur’s father was a Scots-Irish American.
Barack Obama Sr was not an East African American, he wasn’t an ‘American’ anything.
Naturalized after he won the vice presidency, I believe.
The real point - what does Natural Born Citizen mean - will have to be up to a supreme court to decide. Right now precedent is against us - but right now we have a majority of justices who support a strict interpretation...
I give you this - it’ll be an interesting year.
