Well, he’ll be in the same position that Obama was in. There will be some people who are opposed to Cruz’s candidacy and they will try to construct an argument that he is not eligible. They will talk about Vattel and sound like they’re from outer space. They will write books and make money off of persons who dislike Cruz for other reasons. No one else will think that the arguments make any sense and Cruz will lose zero votes because of the issue. In fact, like Obama, he may benefit from the issue because these crackpot arguments will marginalize his opponents in the eyes of voters who like what Cruz has to say.
