Its a bizarre thing, US Presidents claiming heritage to a country they know nothing of, Bush family, Irish, Clinton Irish, Regan Irish, Trump Scottish, Obama Somalian or something, Biden Irish, Jimmy Carter seems about the most normal mix and did not make an issue about it as far as I recall, Carter was a European mix, which you would expect, English, Welsh, Irish, Scots with some German, French & Dutch.
If saying you great great granddaddy was from the old country is a huge vote winner, something is very wrong.

I just don't get how they can have such a strong connection to a country they would not qualify for a passport in.
I am a 1/4 Irish and have zero pull to the old country and would never appropriate Irish culture. I would feel so fake doing it, but Americans do it at the drop of a hat.
I might cheer for them at the rugby, but only after Scotland, England, Wales and the Lions.....and maybe Italy.
