There is no reason to talk about deporting while the border is open. That is like trying to empty the ocean with a spoon. Until it is closed the words mean nothing.
Sadly, you simply don’t get it...or you’re a Rubio “amnesty for 40 million” supporter.
But there is a reason to state that you will not legalize the 11 million to 20 million lawbreakers and that you will enforce our immigration laws including deportation. Attrition thru enforcement.
Failing to mention that sends the signal to those thinking about entering illegally that they should get here before the border is secured. Also, 40% of the illegals got here legally and overstayed their visas, Securing the border only solves part of the problem. We need strong interior enforcement to track and deport visa overstays.
