The drooling halfwit doesn't even know what's going on at the border. Hell, he doesn't know what he had for breakfast. So he has no clue that "kids in cages" is a thing again.
The Democrats want to destroy this country. What better way to do it than bringing in more people than this country can absorb, and turning us into Mexico? The wealthy live just fine in Mexico, it's everyone else who's trying to escape that shithole.
There is absolutely no benefit to allowing mass immigration into this country. There is no magic dirt that transforms people into Americans. They have to be integrated, and that takes time, and it means we have to limit immigration so that the people who come here get integrated into our society. But the Democrats don't want to do that. They want to just open the borders and let everyone in. It's called the Cloward-Piven strategy. The Democrats have been working on enacting the Cloward-Piven strategy for decades, and the mass immigration from poor countries is their dream method of completing it. What better way to overwhelm the USA than millions upon millions of people with little education and no jobs who are going to be given free health care, free housing, free everything on the taxpayer's dime?
The people pulling the strings of the drooling halfwit know that mass immigration will destroy the USA. That's why they're opening the borders. Because they hate America, they hate the constitution, and they hate you.
