The problem for them is its not working. Most Americans according to polls, blame the parents for abandoning their kids or for crossing the border illegally.
Yes, and most people support holding the illegals until they go to court, the support is there for not releasing them if families are kept together.
I am not sure how that will work with the court decisions that say children can only be held a short time. When we have a mass invasion it takes a while for an immigration hearing. Many illegals in the past used to agree to deportation and waive the hearing. Now the special interest groups for open borders are coaching every single one to ask for a hearing.
