Notice, once again, in this standard explanation (used incorrectly by the Trump team, unfortunately), the vague definition of jurisdiction, “taught by law schools.” What law schools? It’s apparent by reading the amendment itself (and not referring to “standard interpretations”) what it means. And furthermore, it’s a known fact that constitutionally something had to be done to negate Taney’s nefarious Dred Scott decision, and this was it. The twisted logic that because this amendment was written to make sure former slaves had citizenship doesn’t automatically mean it only applies to slaves. Rather, it solved a broader problem simultaneously.
