The open borders madness goes all the way back to the Schrub. Both he and Jebby were raised by Hispanic nannies (while Bush 41 was building ZAPATA OIL...say isn't that Mexican?) and have a deep affinity for the folks down south. Jebby's married to the daughter of a migrant worker and they speak SPANISH in their AMERICAN home.
Oh, did I mention that their allegedly REPUBLICAN friends in the Chamber of Commerce just LOVE all that free, off-the-books migrant labor? That the Dems ALSO love that the heavy percentages of those folks become enamored of the DEMS WELFARE SYSTEM and will VOTE DEMOCRAT FOREVER, ensuring that the Pubbies will probably soon never win another election and seems to take the term "SUICIDE PACT" to a new and higher nation destroying level. Suggested new name for the NEW nation: AMERIZUELA!
The open borders/non-enforcement policy has been in effect since GHW Bush.
He was the President who was supposed to implement the enforcement part of the 1986 amnesty bill that was supposed to make another one unnecessary.
He had other ideas.
Since we would not vote to subsume the US to the UN to achieve the New World Order, he would import people who would.
