I still say the wall will be built but ONLY because no red-blooded American would stay in these lower 48 with a female version Mao in the WH. Mexico and Central America will look pretty good at that point.
It’s to keep us IN, not the illegals out.
The main reason I have been against building a massive wall from the beginning is that it can eventually be used to keep people in. I think we have the technologies and system in place already to protect the border. What is missing is enforcement.
Mexico must be empty by now................
