According to the information given (yours and outside sources) there is a grandson born in the US of a citizen of the US and a person of another nation elegible for President of the United States (btw - grandson is mine and my spouse). Why not have the question of eligibility addressed by the SC regarding zer0 and my grandson? It has been tried to bring it before the SC hasn’t it? Thought Alan Keys tried.
Alan Keyes although a candidate on the same ballot as Zero was deemed to have no standing, and as far as I can tell, no human on earth has any standing on this issue.
