Not mutually exclusive. We need both the wall and 100% scanning. Without that, they will just tunnel under the wall or punch holes in it eventually. We need both the wall and full monitoring of the wall. We need to stop this invasion in its tracks.
I’m not naive however. The very next president, either commie Rat or GOP Globalist, will halt all wall construction and flood us with illegals again. BOTH parties want it. Trump is the only barrier to it.
We still need the wall ASAP, and agreed the two corrupt parties are both working against it.
