This is a great summary! This is a case where all the opinions are quite good. I quite like Jackson’s opinion here. The framers of the 14th amendment were radical egalitarians and we shouldn’t lose sight of that.
Nah, the conservative opinions in this case aren't even worth the paper they are printed on. Every single court that saw this case decided the same way: birthright citizenship was intended to work exactly as it has been applied since its inception.
