The solution is very simple and direct. Get a court case going that is high quality enough for the US Supreme Court to consider and rule on. All we need is a favorable Supreme Court ruling to change the 14th Amendment interpretation. Nothing more than that. You don’t need a Constitutional Amendment.
I can just imagine illegal aliens and their backers protesting such a decision. The American people will laugh because it is common sense you don’t give illegal alien babies automatic citizenship. May not be legal sense yet, but it is common sense
