Not settled law. Senate resolution 511 passed saying he was, including a joint legal opinion by Tribe and Olson. The Senate had no business passing such a resoultion, but McCain was nominated and on the ballot without a challenge from the Dems or the GOP.
The issue needs to go to SCOTUS for resolution. Anything else is mere speculation.
Senate resolution 511 was illegal and unconstitutional. I suggest you read the Constitution thoroughly. Screw Tribe and Olson - only God knows how much Soros paid them.
To alter the Constitution requires two-thirds of the States approval. It can take years to make changes or additions.
McCain’s case is most certainly settled law. McCain gets his citizenship via the Immigration and Nationality Act — “by statute.”
