That’s what I think - who the heck is going to toss 30 million people out. The problem wasn’t dealt with years ago when it started happening, so there might be a price to pay for that.
Secure the border, STOP legal immigration from south of your border, throw out EVERYONE who has had trouble with the law, then start looking at what to do with the rest. No welfare, no healthcare, no driver’s licenses, no voting for ANY of them. They might self deport.
They figured out how to get here they can figure out how to go home, I will show them the direction South if they need help with that. Self deportation works, the employers need to be given punitive fines.
