With 20,000 shoulder-fired missiles, each capable of bringing down a commercial airliner, missing from Libya dealing with our porous borders is a matter of urgent national security. This is an issue apart from illegal immigration and it should not be coupled with any of those issues.
If the border is secured the illegal immigration problem will fix itself over time through attrition if by no other means. Hence coupling border security with illegal immigration is a way for liberal Democrats to once more con the Republican Party into giving them what they want. Idiots like McCain fall for it every time.
