Obama “can” claim Scots-Irish heritage, but he has not and likely will not. He is trying to convince African-Americans that he is Black-enough to be embraced by them. When he does discuss his being partially White, it is in jest. Like he is Dick Cheney’s cousin, or his grandmother is a typical white person (afraid of Blacks). etc.
His identity politics leaves him without an identity.
Just the IDEA of Obama the Magic Negro claiming Scots-Irish heritage after playing the race card every day for the past two years is hysterically funny.
I don't see why. After all, he's got an Irish last name.
