40% of the illegal aliens come here legally and overstay their visas. Securing the border only solves part of the problem. We need a system to track and deport visa overstays.

I would lay 10 to one odds that the system of tracking you want is already in place, and I say that without any particular knowledge of the system.
What we need is a President who will permit the tracking to actually take place, and who will also permit the border enforcers to take action upon the information. That is what has been lacking. Obama has been the worst, but Bush wasn’t much better in that regard.
