The 14th Amendment: “All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States and of the State wherein they reside.”
Most people just glaze over the “and subject to the jurisdiction thereof” wording as meaningless legal jargon, but it’s the most important part. It was added by the author of the citizenship clause, Sen. Jacob Howard of Michigan, specifically to prevent anyone from misinterpreting it to imply any kind of birthright citizenship for foreigners. He went out of his way to clarify this from the beginning: “This will not, of course, include persons born in the United States who are foreigners, aliens, who belong to the families of ambassadors or foreign ministers.”
This was also emphasized by the Supreme Court in Elk v. Wilkins, in which it acknowledged that the 14th Amendment does not give citizenship to Native Americans, because they were subject to tribal jurisdiction, not U.S. jurisdiction.
But this is irrelevant to the “make up whatever you feel like” left, which cannot advance its agenda and import tens of millions of new Democrat voters unless the Constitution is discredited, marginalized and bastardized into something completely different from what the Founders put in place. The facts get thrown under the bus just as quickly as the rule of law, public safety, fiscal sanity, and everything else that gets in the way of Democrat power.
Never mind the fact that this invasion of foreign criminals breaking into our country is bankrupting our welfare programs, crowding our prisons, bleeding our school systems dry, overwhelming our hospitals, discouraging legal immigration and driving state and local budgets into the ground. Democrats have elections to win, so there is nothing else to think about.
