Man that's gonna look great when a future Democrat President, probably a Latino one, has a "tear down this wall" moment and attacks it with a sledgehammer.
You do realize that's exactly what is going to happen right? One it is built (it won't be but humor me) it will have to be maintained forever. That will require a Democratic buy in for when they win the Presidency. Absent that, get ready for "Berlin Wall: America Edition".
So what's your plan to get Democrats on board?
Democrats should just thank you wall people now. You're custom designing a bonafied historic moment for a Latino-Obama figure that will be seized upon, much to your horror.
But then again, people actually want walls are kind of Strategy Dumb to begin with.
