I believe Congress could pass a “clarifying resolution” and fix the problem overnight?

Maybe. Something like limiting it to children born here of legally present permanent residents.

The 14th Amendment clearly says, "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, ..."

Illegal immigrants are NOT subject to any jurisdiction. As proof, order them to report to the nearest police station or city clerk's office. What, no stampede?
