>>The problem isnt tracking legal immigrants<<
There certainly is a problem tracking those who initially hold legal visas (but after the overstay their visas the become illegals). After McCain pledged to secure the border first at CPAC, he did not vote for the Sessions amendment that would have established a visa exit tracking system.
I meant that the people opposed to illegal immigration don’t oppose a plan to track legal immigrants.
Of course not. The goal is to get them here, not to make sure they leave.
