Moving the needle a bit doesn't solve the problem. The dems and RINOs felt that it moved the perception that the problem was being dealt with. Like Race says it was an intelligence test which you Harrisbros failed.
No one said that it would solve the problem, but like everything in life, you keep moving the needle a bunch of times, then it starts to solve the problem.
using your standard, we shouldn’t build a wall either because that will also not solve the problem. The hope is building that wall would move the needle a bit as well. See how that works?
The solution isn't complicated.
Remain in Mexico
Build a complete wall from San Diego to Brownsville, and put barbed wire on the top of it
Start mass deportations. Start with the major criminals, then the low level ones, then the folks who are living on the government's dime.
Give the "fine people" 18 months to get their green card or citizenship in order. After that, you're gone. No warning, just gone.
