The Constitution does no such thing.
Article IV, Section 4. You seriously don't think securing our borders is the job of the MILITARY? Hello, you've succumbed to leftist stupidity and lies. The MILITARY? You don't grasp the relation between
the military and
securing our freaking borders?
You are S-T-U-P-I-D. Not ignorant, stupid
Here's the text of Article IV, Section 4:
The United States shall guarantee to every State in this Union a Republican Form of Government, and shall protect each of them against Invasion; and on Application of the Legislature, or of the Executive (when the Legislature cannot be convened) against domestic Violence.
Now, I'm not sure what school of Constitutional interpretation you fit within, but what do you believe that the founding fathers meant, when they said "foreign invaders"?
Do you think they meant a military invasion, or do you think they meant immigrants?
Keep in mind, the founding fathers never expected any "controls" whatsoever on immigration.
To think they meant to apply that to immigrants takes quite a reach, for the sake of legal interpretation. I doubt you could even get Stevens to go that far from the text.
