Simply enforcing the laws against the hiring of illegals would go a long ways towards removing a large proportion of the illegals.. Some physical force will be necessary and citizens should be trained in picking them up.
I wouldn’t be surprised if widespread dissemination of this poll caused some of the illegals to self-deport.
Ending remittances would work even faster. End welfare of all kinds for illegals and their anchor babies and watch them self deport. The howls from the governments of the various coun tries from which these scofflaws come would be music to my ears.
