My understanding is America doesn’t acknowledge the concept of dual citizenship. If you’re a citizen here you’re a citizen here, pay your taxes or else. What other countries want to believe about you isn’t our problem.
Really we can’t ban people from being president just because of dual citizenship. Since we have no control over other countries’ definitions of citizenship. If we banned dual citizens other countries could invalidate our candidates just by declaring them citizens.
It’s not an issue of whether he would be legally ‘banned’ from being President — it’s that being acknowledged as a dual citizen (and having withheld that info from the public) could very likely harm his electoral prospects..... especially with some of those “bitter” white working class drones so despised but so needed by Obambi.... you know, the ones still “clinging” to their religion and guns. Some of THOSE people might not be inclined to vote for a Kenyan (or Indonesian) citizen to be POTUS. Shame on them. /s
