Immigration is an issue on which reasonable people can hold a broad spectrum of opinons. I am not discussing immigration here.
Illegal immigration is another thing altogether. I consider it a 'wingless' issue. There is no right-wing position nor left-wing. It is an elegantly simple problem at it's base. It behooves us all to control/monitor those who enter into and/or live in our country. This is true for any number of reasons. It is also benefits the very people we scrutinize.
What more would we need to know?
