I’m sick to death of the phrase, “constitutional conservative.” You do know, don’t you, that your Mr. “constitutional Conservative,” was dead wrong on the 14th Amendment and Donald Trump was correct. Even Mark Levin said so. SO, put that ‘consitutional conservative” crap in your pipe and smoke it.
There are two schools of thought on constitutional law. There's the "original intent" school, which asks what the intended purpose of the amendment is, and then there's the "letter of the law" school. From an original intent point of the view, the 14th amendment does not guarantee birthright citizenship to foreigners who are here, especially not those here illegally. The intent of the law was to grant citizenship to former slaves and their children, not to give it to children of illegal immigrants.
However, a "letter of the law" reading means what it says: if you're born here, you're a citizen. Unfortunately, the Supreme Court has decided in favor of this interpretation. I don't like it at all, I disagree with it, but it isn't "wrong" from a legal point of view.
