There's way too much gum flapping going on, and not enough solutions being proposed.
Scouts Out! Cavalry Ho!
You are likely correct. For what it is worth, I would propose a difficult to achieve simple solution. Enact the following paragraph into law.
Following the date of enactment of this legislation, a non United States Citizen who enters the United States without authorization under a law enacted pursuit to Article I of the United States Constitution or any non United States Citizen who remains longer than one year after enactment in the United States following an earlier entry without authorization under a law enacted pursuit to Article I of the United States Constitution shall never be eligible for citizenship or legal residency. This bar may only be removed by legislation enacted pursuit to Article I of the United States Constitution. Courts established by Congress under Article III of the United States Constitution shall be limited in jurisdiction under this law to questions of the individuals citizenship status at the time of entry and the date of entry.
If this were to be made into law, it would remove the incentive for the current wave of child immigration and would encourage those currently here to return home and pursue legal entry. It would also take away the President's power to subvert the law and the courts' power to hamper enforcement. Probably not going to happen, but it would allow someone in Congress to call the bluff of the gum flappers.
The left is on another “Long March.” These kids are the next generation’s reliable democrat voters.
