So then according to Levin Bobby Jindal and Marco Rubio are not citizens at all, much less natural born citizens?
It’s the law.
They’re not NBCs that’s for sure.
I think you would get different answers from different people. However, we have the practice of illegal aliens as well as legal non-citizens giving birth in America and these children have citizenship. I would be fine with a law, not a constitutional amendment, that clearly defines citizenship. We already have a law that excludes certain classes of people born in the US from citizenship. As for the natural born part of your question, there needs to be better definition of that from the courts or a constitutional amendment that clarifies the definition.
